An Extensive Look At Suspension

0602sc_suspgen_01_z 1/116

The 1913 "Little Six" (marketed along side the Chevrolet Six by the Republic Motor Company) is a perfect example of early suspension technology. Up front was the state-of-the-art (for the time) semi-elliptic front spring setup and in the rear a kind of unique design called 3/4-platform suspension. As you can see, the 3/4 platform design used a front-hinged frame to support the rearend with a transverse leaf attached at one end (making up the third quarter) to provide flexibility.

From what I understand, back in mid-1904 the experiences of a young man named William Brush helped to initiate advances in automobile suspension systems that led them well on their way to becoming what they are today. His discovery, or rather its prelude, was the result of a mishap while hot roddin' in his brother's car. Brush was rolling along way too fast for the inadequate unpaved roads of the day and hit a turn at around 30 mph.

Midway through the turn the right front wheel skidded off the road into a rut and immediately began to shudder violently. The undulations of the jolted right front elliptic leaf spring sent shock waves across the solid I-beam axle causing the entire frontend of the car to shake furiously. Brush was unprepared for the situation and lost control, crashing through a fence and flipping over in a cow pasture.

Later that day, the youngster admitted what had happened to his older brother, Alanson, who was rightfully pissed off. Luckily for him Alanson was in the process of planning improvements to his creation, a car dubbed the "Brush Two-Seat Runabout," which finally hit the market in 1906. It featured a revolutionary (for the time) suspension system that incorporated two innovations which, up to this point, had never been used together--front coil springs and shock absorbers--all mounted to a flexible hardwood axle.

0602sc_suspgen_02_z 2/116

This is a production version of a Brush Runabout similar to the one mentioned earlier (though this is a four-seater).

Back then, some European carmakers had already been experimenting with coil springs, with Gottlieb Daimler in Germany being the leading advocate. However, most manufacturers stuck with leaf springs; they were less costly, and by simply adding or removing leaves or changing the shape from full elliptic to three-quarter or half elliptic, the spring could be made to support varying weights.

Leaf springs in one form or another have been used since the Romans suspended a two-wheeled cart on pliable wooden poles. The first steel spring put on a vehicle was a single flat plate installed on carriages by the French in the 18th century. Leaf springs as we know them today were invented by Obadiah Elliot back in London around 1804. He simply piled one steel plate on top of another, pinned them together and shackled each end to a carriage, which worked pretty well.

0602sc_suspgen_03_z 3/116

Here is a shot of yet another Brush. In this shot you can see both the wooden front axle and the pair of coil springs, this was high-tech handling technology back in the early 1900s.

Henry Ford's 1908 Model T Ford featured leaf springs with a novel twist, using only one spring at each axle, mounted transversely, instead of one at each wheel. Ford's adaptation of high-strength vanadium steel from a French racing car allowed him to save weight and cut costs in many areas of the Model T without compromising its durability.

The coil spring ain't no spring chicken, either. In fact, the first patent for such a spring (British Patent No. 792) was issued to a guy by the name of Tredwell in 1763. The main advantage of coil springs was that they did not have to be spread apart and lubricated at regular intervals to keep them from squeaking, as leaf springs did.

With the exception of a car here and there, independent coil spring front suspension remained in limbo for 25 years after the introduction of the aforementioned Brush Runabout. Then suddenly in 1934, GM, among others reintroduced coil spring front suspension, this time with each wheel sprung independently. In that year, most cars started using hydraulic shock absorbers and low-pressure tires, as well. The combination of solid front axles, shocks and balloon tires really aggravated frontend shimmy but the new practice of suspending each wheel individually lessened the effects of spring bounce. Soon after WW II, nearly all manufacturers switched to coil springs for the front wheels.

0602sc_suspgen_05_z 4/116

This is a zoomed in image of the 3/4 platform setup from the lead image. You can see how the parallel portions support the rearend housing pivoting on what look to be traditional front leaf-type mounts and the rear portion tied together with a multi-leaf spring

Buick became the first U.S. manufacturer to use rear coils back in '38. Manufacturers have vacillated between leaf and coil springs since then and it's been kind of a rule-of-thumb that large, heavy cars are equipped with leaf springs, while small light cars use coil springs.

Fast forwarding to the present day we see IFS as the norm and IRS as a bit more exotic. The musclecars we all know and love for the most part have received upgrades above and beyond what was offered as original equipment and through the balance of this issue we'll hopefully offer you some useful insight into both the theory and the availability of the systems and products that make your super Chevy a joy to drive.

SUSPENSION
What is it and how does it work?

0602sc_susp1_01_z 6/116

Though equipped with IFS from the factory the stock suspension and steering in our beloved muscle cars normally leaves much to be desired. The aftermarket has come to the rescue with a plethora of bolt-in components and complete replacement assemblies that help us put real performance in our performance cars.

Not counting tires, your suspension is about the only thing that separates you and your vehicle from the road. No matter how smooth you think a road is, it's a pretty darn rough place to propel over a ton of metal at high speed. We rely upon our vehicles suspension to cushion both our cars and ourselves from the road, or track, whichever the case may be. Suspension also serves to help transmit horsepower to the ground, letting us take full advantage of our performance drive trains. In it's most basic form, suspension consists of a few basic components like springs, shocks, and anti-roll (sometimes called sway) bars.

Springs
In our niche springs come in three types: coil springs, torsion bars, and leaf springs. Coil springs are what most people are familiar with, and are actually coiled torsion bars. Leaf springs are what you would find on most domestic cars up to about 1985 (and almost all heavy-duty vehicles). Leaf springs are strips of spring steel stacked and connected to the axle. The strips are called leaves, hence the name. The torsion bar is a bizarre little contraption which gives coiled-spring-like performance based on the twisting properties of a steel bar, something not seen very often in our hobby (except on some early '60s Chevy pickups). And coil springs are just what their name implies - springs made from a round bar of steel twisted in an upward spiral shape.

0602sc_susp1_02_z 7/116

Out back we've really got a bunch of suspension options at our disposal. No longer are we relegated to using standard coils or leaf springs and adding traction aids we now have options such as the popular four-bar design.

Shocks
Actually, the name shock absorber is a bit of a misnomer. The correct description should actually be dampers as they actually dampen the vertical motion induced by driving your car along an uneven surface. If your car only had springs, it would bounce along the road like a pogo stick. Shocks perform two basic functions. They absorb any larger-than-average bumps in the road so that the shock isn't transmitted to the car chassis, and they dampen the rebounding action of the springs. Being velocity-sensitive devices the faster they move, the more resistance there is to that movement. They work in conjunction with the springs. The spring allows movement of the wheel to allow the energy in the road shock to be transformed into kinetic energy of the un-sprung mass, whereupon it is dissipated by the shock absorber.In the performance end of automobile suspension we're beginning to see a surge in the use of coilover shocks. Coilovers consist, as the name implies, of a shock and a coil spring together as one assembly. Most offer adjustable spring plates that can be adjusted to make the springs stiffer and looser, and adjustable damping valves used to adjust the compression damping of the shock absorber.

0602sc_susp1_03_z 8/116

Another rear suspension option we can entertain is the tried and true ladder bar setup.

Coilover's are a basic component of many performance suspension systems we're adapting to our muscle cars these days. Most all aftermarket frames and frame stubs (both front and rear) make use of coilover shocks, be they used for IFS, IRS, ladder bar systems, four-link systems, and/or four-bar systems. This is mainly because standard coil springs (though they are available with either fixed constant rates or with variable rates) cannot be adjusted for varying loads as most performance coilover units can. Spring selection on independent suspensions, at first glance, seems to be a daunting task. But, in reality, it is just a matter taking some measurements and plugging them into a basic formula.

* Motion ratio at the tire is (A/B)2.
* Measure the distance from the pivot point of the a-arm to the center of the mounting point of the shock and spring combination (A). .
* Measure the distance from the pivot point of the a-arm to the center of the tire tread (B).
* For example if A=14 and B=18. Apply these dimensions to the formula as follows: (A/B)2 = (14/18)2 = .61.
* .61 is the motion ratio percentage at the centerline of the wheel and tire combination. .
* Divide the .61 into the weight at the wheel to determine the amount that the spring is holding up at that location, and select the corresponding spring.

0602sc_susp1_04_z 9/116

For those that plan on campaigning their cars on the strip as well as running 'em on the street the four-link setup provides much more in the way of adjustability than its counterpart the four-bar system.

Air Ride Suspension
Air ride, as its name implies, is a suspension system that uses air rather than metal springs to support the vehicle and control ride motions. Air springing results in a smoother ride, because the natural frequency of vibration of an air spring does not vary with loading as it does with metal springs. Air springs can be made very soft for the lightly loaded condition and the pressure automatically increased to match any increase in load, thus maintaining constant ride and handling quality. An airbag/air spring is constructed of rubber and a high strength fabric. Numerous styles, sizes, and capacity ratings are available, and their load capacity and ride height are varied by air pressure.

Sway Bars
A sway bar (also called an anti-sway bar or anti-roll bar) is an automobile suspension device that connects opposite (left/right) wheels together and acts as a torsion spring to couple the vertical motion of the wheels on one end of the car more, and to reduce body roll in corners. When the body begins to roll, it acts on the sway bar to transfer some of the excess weight from the outside wheel to the inside one. The effect of these motions is reduced body lean and improved traction in corners. Increasing the stiffness (usually by increasing the thickness, but occasionally shifting the mounting points to provide a different degree of leverage) of the bar on one end of the car tends to increase the amount of traction of the other end during turns. Any time you alter a vehicle's ride height you change its center of gravity, and a good suggestion to compensate for the handling change is to upgrade the anti-sway bars. As a good general rule, any time you add an anti-sway bar or upgrade an existing bar you will receive a noticeable improvement in the way your vehicle handles.

 

Front Suspension

0602sc_sfpr1_30_z 10/116

A Chassisworks frame will remove up to 300 pounds of excess weight from your car or truck. Since these unique designs use a straight front crossmember, the hub width is infinitely adjustable. Now you can position your wheels at whatever width you need (minimum of 50") to maintain the correct track for your vehicle. Our exclusive adjustable upper mounts allow 3"of ride-height adjustment. These frames use Mustang II or Chassisworks fabricated spindles and our Mustang II upper and lower A-arms (available in silver-powder-coat; chrome; or plain finish) and lightweight Pinto racks. We package these components unassembled, for lower freight charges. They do not require a jig to install. Excellent instructions and assembly drawings are provided. To make at-home installation even simpler, we also offer an easy-to-use assembly fixture (Number 6706). Three frame styles are available. The 1-5/8"x.134 and 3x2x.083" frames must be tied to the roll cage with forward struts. Our rectangular frames were designed for use in street rods and Pro Street machines that do not allow forward struts to tie into the roll cage. These heavy-duty, 3x2x.120"-wall models include a 3x2" front crossmember and Mustang II rack and pinion (which is stronger than Pinto steering). Three ride heights (3-1/2; 4-1/2; & 6") are available.

PRO STREET FOUR-LINK

0602sc_srpr1_34_z 24/116

Our popular Pro Street 4-link uses the same bracket geometry as our Battle Cruiser 4-link. Instead of spherical bearing rod ends, it uses billet-steel rod ends with urethane bushing liners. In addition, one end of the link tube uses a urethane-lined weld eye, which virtually eliminates the possibility of the rod end rattling, causing the link bar to fall off. The bars are direct-thread, 1-1/4x.156" tube to accommodate the huge, 1"-shank, billet rod end. These rod ends are strong enough for blown street cars and offer plenty of flexibility for a street-driven vehicle. Pro Street 4-links are available with blue-powder-coating or chrome-finish link bars.

Housing Floaters Eliminate Suspension Bind

0602sc_srpr1_05_z 25/116

When using ladder bars with a leaf spring rear suspension, the axle housing cannot be rigidly attached to the springs. If it were, severe binding of the rear suspension would occur because the Ladder Bar and the leaf spring both travel in separate competing arcs. By allowing the housing to rotate and glide on the leaf spring, the Floating Housing Mount eliminates the bind and allows the Ladder Bars to work the way they were designed.

Competition Engineering Traction Bar Limits Axle Rotation

0602sc_srpr1_22_z 41/116

The bolt-on "Slapper Bar" is one of the most basic traction devices available. Originally pioneered by Bill "Grumpy" Jenkins in the mid-sixties, it gets its name from the way it works. One end of the Traction Bar replaces the stock spring pad and is clamped to the rear axle housing. The front end of the bar is suspended just below the spring eye. When the housing begins to rotate during launch, the bar also rotates until it contacts or "slaps" the spring. (Unlike other brands, Competition Engineering Traction Bars make contact directly below the front spring eye, preventing spring damage). When contact occurs, the Slapper Bar becomes a lever trying to push the axle housing down and planting the tires in the process. Competition Engineering, 80 Carter Dr., Dept. SC, Guilford, CT 06437, 203-453-5200, www.competitionengineering.com.

 

How Ladder Bars Work

0602sc_srpr1_24_z 42/116

The Ladder Bar is a more sophisticated traction device because it serves as an extremely rigid, bridge-type truss that locates the rear axle housing directly to the chassis. With the axle housing held firmly in place, the torque applied to the differential is now transferred immediately through the Ladder Bars and into the chassis. By using the Ladder Bar to carry power to the chassis, the front end reacts by rising. As the front of the car travels upward, rapid weight transfer is created which "plants" the rear tires and propels the car forward. Competition Engineering, 80 Carter Dr., Dept. SC, Guilford, CT 06437, 203-453-5200, www.competitionengineering.com.

POINT & SHOOT

Making That Musclecar Handle

0602sc_suspsteer_01_z 46/116

This bad boy looks as though it could use a bit of help. Though in its original form the OEM suspension and steering was passable for everyday commuting it certainly needs a bit of aftermarket help to become a good handling ride.

During a recent conversation with an industry professional we got around to the subject of making old musclecars handle like new cars. "It's pretty simple," he said, "Install a quick-ratio power steering box, new springs, polyurethane bushings, and some fat wheels and tires, and you'd be surprised at how responsive an old car could be. You really can improve the handling of any car with the addition of some trick new steering components, suspension components, and the right tires and wheels."

Most of our favorites were built at a time when handling was far a main consideration. Thirty years ago, straight-line get-up-and-go was all it took to sell cars, so the manufacturers concentrated on muscle. It was also around that time that power steering became a must-have performance option, even though it was still considered a "luxury" item. Even then, however, most musclecars came with a power steering setup that was about as useful as breasts on a bull. Thankfully, in this day and age there's a plethora of bolt-on steering components made for just about every car.

0602sc_suspsteer_02_z 47/116

The addition of a good, tight, quick ratio box steering response will improve tremendously.

In order to get better handling and a quicker response from our classic Chevy the first thing we need is a better steering box. "What makes a steering box better than another", you may be asking? Well, it's a matter of ratio. Stock boxes usually sport a ratio of around 16 or 17:1, some could even be as much as 20:1, but don't be fooled, in this case more is definitely not better. Aftermarket or performance boxes are usually around 12:1. What does that mean? Simply put, a 12:1 steering box is "faster," it'll translate more steering wheel movement to the front tires than a 20:1 box would. So when you turn the wheel a quarter turn with a 12:1 box, the front wheels will move further than they would with that same quarter-turn with a 20:1 ratio box.

0602sc_suspsteer_03_z 48/116

Performance-grade springs and shocks will complement the addition of an updated steering gear more than you might imagine.

The same theory holds true with most rack-and-pinion steering systems found in performance cars today. Most stock racks use around a 13:1 ratio, but performance aftermarket racks can be ordered with anywhere from an 18 to 4:1 ratio, again, a heck of a lot quicker than stock. The rack-and-pinion's compact and lightweight design makes it a very easy-to-package system that's good for high-performance driving, as well.

One problem with using high-performance power steering racks and boxes in early cars has been finding the right power steering pump to do the job. Today there are plenty of pumps to choose from, but adapting a late-model pump to an early musclecar used to require custom fabrication. Many aftermarket companies have addressed that problem and now it's an easy swap to do. There are bolt-on brackets and pulleys available, and many sources provide high-pressure hoses to make the swap, as well.

0602sc_suspsteer_04_z 49/116

Keep in mind though, upgrades of any kind aren't going to do you any good if your frontend components are worn. A frontend rebuild should be the starting point for any handling upgrade task.

The finishing touch for a new steering system comes from the use of a new collapsible steering shaft along with a vibration-reducing U-joint to get rid of that worn-out old rag joint. Though available in numerous lengths more than likely an aftermarket shaft will require cutting to fit. It's also wise to drill a few locating dimples for each of the shaft's set screws to help secure the shaft in place. The nice thing about these shafts is they're smaller and lighter than the clunky stock pieces, making spark plug and header clearance easier to deal with.

Updating your old steering components and installing some new high-tech parts is a bit more than an afternoon job, but the effort can make any classic Chevy handle tremendously better than it did.

 

STEERING SYSTEMS EXPLAINED

The Same Thing, But Different

0602sc_suspsteer2_05_z 50/116

Steering and suspension are two automotive systems that perform different functions yet are directly related. Each one exerts such an extreme amount of control over the other that it's rare one is mentioned without reference to the other. Let's start out by taking a look at the steering system.

0602sc_suspsteer2_01_z 51/116

This illustration represents the common mechanical (or recirculating ball) steering box.

STEERING
When it comes to getting your musclecar to head in the direction you want it to, there's two basic systems that'll get the job done: mechanical gear (sometimes referred to as recirculating ball) and rack-and-pinion steering. Both can be found in either manual or power-assisted versions.

MECHANICAL
Standard mechanical steering uses a series of arms and links connecting both front wheel assemblies so they move in unison. In a steering box, the input shaft turns a worm gear that, in turn, causes a toothed metal block to move back and forth. Ball bearings in a recirculating track reduce the friction between the worm gear and the block. As the block moves, its teeth rotate a gear connected to a shaft (the Pitman shaft), which then, via the Pitman arm, moves the balance of the steering linkage, and hence, turns the front wheels. In a nutshell, here's the whole picture: the steering wheel is connected to a shaft (the column), at the other end of the shaft is the box. The steering box has an arm attached to the output shaft called the Pitman arm. The Pitman arm is connected to one end of the center (or drag) link. At the other end of the link is an idler (a fixed pivot point), between the idler and the Pitman arm the centerlink is supported in the correct position to keep both front wheels moving in unison.

0602sc_suspsteer2_02_z 52/116

This is representative of the components that make up the complete steering system.

Attached to either end of the centerlink are inner tie rods that provide pivot points for the steering gear. At the opposite end of threaded tubes called sleeves are, as the name implies, outer tie rod ends (the threaded sleeves allow the tie rod ends to be adjusted in or out as needed so that the wheels can be aligned). The outer tie rod ends are connected to the spindle assemblies that actually turn the wheels. The spindles (or knuckles as they're sometimes called) are connected to control arms via upper and lower ball joints creating the geometry of the steering axis.

See, it's not so complicated. It's just a simple connection between the steering wheel and the front wheels of the vehicle. In the mechanical system the weakness falls at the pivot points. The pivots are ball and socket joints that do, over time, wear out and require replacement. Worn steering parts degrade handling and promote premature tire wear, as well.

0602sc_suspsteer2_03_z 53/116

Rack-and-pinion steering is known for being more precise in operation than the standard mechanical system, primarily because it utilizes many less components and joints.

RACK & PINION
Though it performs the same job, rack-and-pinion steering does the task in a different manner. Basically, it combines the steering box and center link into one unit. Like mechanical steering, the wheel is connected to the rack-and-pinion via the steering column. At the base of the column (inside the R&P assembly) is a vertical gear called a pinion. The pinion rotates with the steering wheel (via the column) and its teeth mesh with a horizontal toothed shaft called a rack. As the pinion rotates it in turn moves the rack back and forth (left and right). Attached to each end of the rack are threaded rods (inner tie rods) to which the outer tie rods are connected. Again, like mechanical steering, the outer tie rods connect to the spindles (knuckles) holding the wheels.

This illustration portrays a power-assisted rack-and-pinion.

One of the advantages rack-and-pinion steering has over its mechanical counterpart is that its more precise--in other words, input rotation is interpreted and transferred with virtually no "slop" or wasted energy because it makes use of significantly fewer parts and pivot points than that of standard "box" mechanical systems. This precision translates into much more responsive steering action.

Basic Alignment and Geometry

0602sc_suspolystpr3_01_z 55/116

Positive caster has the lower ball joint pivot slightly ahead of the center of the wheel and the upper ball joint tilted toward the rear of the vehicle.

What is wheel alignment?
Alignment (also known as front-end geometry) refers to the position of the front wheels relative to each other, the ground, and to the vehicle. Correct alignment must be maintained to provide safe, accurate steering, vehicle stability, maximum performance, and minimum tire wear. The factors that determine wheel alignment are mutually dependent. Therefore, when one factor is adjusted, the others must be adjusted to compensate, as well. Here we'll attempt to shed a bit of light on the subject relative to your performance vehicle.

There are basically four critical factors that make up correct steering geometry; Caster, camber, toe, and inclination. All, as stated above, are co-dependant and the correct orientation of each meld to provide optimum control and drivability in any vehicle, performance oriented or not.

0602sc_suspolystpr3_02_z 56/116

Positive camber means the top of the wheel is slanted slightly away from the vehicle so that when loaded, the wheels will be approximately vertical.

Caster
Caster is the orientation of a line, drawn through the center of the upper and lower ball joints and viewed from the side, can be tilted forward or backward. Positive caster means that the top of the upper ball joint is tilted toward the rear of the vehicle, and negative caster means that it is tilted toward the front. A vehicle with a slightly positive caster orientation will have its lower ball joint pivot slightly ahead of the tire's center. This will assist the directional stability of the vehicle by causing a drag at the bottom center of the wheel when it turns, thereby resisting the turn and holding the wheel steady in whichever direction the vehicle is pointed. A vehicle with too much (positive) caster will be hard to steer and shimmy at low speeds. A vehicle with insufficient (negative) caster may tend to be unstable at high speeds and may respond erratically when the brakes are applied.

Camber
Camber angle is the number of degrees that the wheel itself is tilted from a vertical line, when viewed from the front. Positive camber means that the top of the wheel is slanted away from the vehicle, while negative camber means that it is tilted toward the vehicle. Normally a vehicle will have a slight positive camber when unloaded. Then, when the vehicle is loaded and rolling down the road, the wheels will just about be vertical. If you started with no camber at all, then loading the vehicle would produce a negative camber. Excessive camber (either positive or negative) will produce rapid tire wear, since one side of the tire will be more heavily loaded than the other side.

0602sc_suspolystpr3_03_z 57/116

Steering inclination along with caster is responsible for directional stability and the self-centering characteristics of the steering

Toe
Toe-in is the difference (in fractions of inches) between the front and the rear of the front tires. On a vehicle with toe-in, the distance between the front wheels is less at the front than at the rear. Toe-in is normally only a few fractions of an inch, and is necessary to ensure parallel rolling of the front wheels and to prevent excessive tire wear. As the vehicle is driven at increasingly faster speeds, the steering linkage has a tendency to expand slightly, thereby allowing the front wheels to turn out and away from each other. Therefore, initially setting the front wheels so that they are pointing slightly inward (toe-in) allows them to turn straight ahead when the vehicle is under acceleration.

0602sc_suspolystpr3_04_z 58/116

Forward motion stretches steering linkage allowing the wheels to be forced out and away from each other. Toe-in allows a vehicle's front wheels to roll in parallel, as they should.

Inclination
Steering axis inclination is the number of degrees that a line drawn through the upper and lower ball joints (or strut and lower ball joint) and viewed from the front is tilted to the left or the right. This, in combination with caster, is responsible for the directional stability and self-centering of the steering. As the steering knuckle swings back and forth from lock to lock, the spindle generates an arc, causing the vehicle to be raised when it is turned from the straight-ahead position. The reason the body of the vehicle must rise is straightforward: since the wheel is in contact with the ground, it cannot move down. However, when it is swung away from the straight-ahead position, it must move either up or down (due to the arc generated by the steering knuckle). Not being able to move down, it must move up. Then, the weight of the vehicle acts against this lift, and attempts to return the spindle to the straight-ahead position when the steering wheel is released.Why is proper wheel alignment so important?

In the long run, it will prolong the life of your car, and save you money, and just as importantly to us, increases and optimizes handling and street performance. As a bonus, especially these days, correct wheel alignment results in better fuel mileage, and it actually extends tire life on rear tires as well as front tires. In fact, the most common cause of unusual tire wear is improper alignment.

Ackermann is a geometric arrangement of linkages in the steering designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.

The Ackermann principal
There is another geometric factor that plays a part in automotive handling called Ackermann. It's primarily relegated to slow-speed maneuvering and early, more rudimentary steering systems but it is worth mentioning here.Ackermann is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. In other words, when a vehicle is steered, it follows a path that's part of the circumference of its turning circle, which will have a center point somewhere along a line extending from the axis of the fixed rear axle. The steered wheels must be angled so that they are both at 90-degrees to a line drawn from the circle center through the center of the wheel. Since the wheel on the outside of the turn will trace a larger circle than the wheel on the inside, the wheels need to be set at different angles.

The Ackermann steering geometry arranges this automatically by moving the steering pivot points inward so as to lie on a line drawn between the steering kingpins and the centre of the rear axle. The steering pivot points are joined by the tie rod, or a rack and pinion, this arrangement ensures that at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.

"G-Force Spindle" For GM Muscle Cars

0602sc_suspolystpr_10_z 68/116

Hot rodded muscle cars are hotter than ever, but the demands of modern traffic have made their chassis shortcomings all too apparent. The sad truth is that most modern family cars can out handle and brake our beloved '67-'69 Camaros, '68-'74 Nova, and '64-'72 Chevelles, but easy bolt on help is available! Fatman's new G-Force spindle provides a 2" drop for a lower center of gravity, and has the upper ball joint raised 2" to obtain the improved camber curve necessary properly plant those wide, sticky modern radial tires. A 20% improvement in skid pad numbers has been observed. The steering arm position has been optimized to eliminate bumpsteer. Any disc brake system that fits the stock spindle will fit these new ones, so the sky and your wallet are the only limits to improved braking. The G-Force dropped spindle will align properly with either stock stamped control arms, or Fatman's tubular arms, in either stock width or narrowed versions. Upgraded shocks, springs and sway bars are also available to further the improvements. A couple hours work will transform the handling of your muscle car-it can handle as good as it looks! For more info, contact the Fatguys at 8621-C Fairview Rd, Hwy 218, Dept. SC, Charlotte, NC, 28227-7619. (704) 545-0369 or www.fatmanfab.com

 

Camaro 2" Dropped Spindle

0602sc_suspolystpr_11_z 69/116

HEIDT'S Hot Rod Shop now offers Improved Camber 2" Dropped STEEL Spindles for the first generation `67-`69 Camaro. This spindle is very different that other spindles on the market. It is called an "Improved Camber" spindle because the upper ball joint is raised the optimum amount, which is 1-1/2". These are not some factory adapter spindles, but are new, specifically designed spindles for the Camaro. The raised upper ball joint means that the arc that the upper control arm swings in is now different than the factory design, so it yields a different camper change during suspension movement. You cannot do this with any "special modified" control arms, as the pivot points are determined by the ball joint locations on the spindles. The control arms just "connect the dots" and go along for the ride. Period. As the car leans into a turn, the new camber characteristics keep the tire from leaning outward, keeping the tire patch in full contact with the road. This means more stability and higher performance during cornering. Along with that, this spindle is manufactured, as are all of HEIDT'S dropped spindles, from STEEL, not cast iron. These spindles are the strongest ones in the industry. At some point all cars must stop. HEIDT'S spindles again set the standard with their factory bolt-on caliper brackets. Do you want standard disc brakes with factory calipers, polished billet calipers and hubs, or the monster 13" rotors with huge 6 piston calipers? All these brake packages are available for HEIDT'S spindles because the caliper brackets bolt on.For more info call HEIDT'S at 800-841-8188. Or www.heidts.com

 

Power Steering Pumps

0602sc_suspolystpr_12_z 70/116

Vibration reducers

0602sc_suspolystpr_13_z 71/116

Vibration reducers are a necessity in your car if you are driving the car on the street. Every new vehicle purchased today has some type of a vibration reducer incorporated into the steering system. The original type referred to as either the "rag joint" or the "factory style" coupler. Over the years, Borgeson developed the "In line" vibration reducer and our most popular Vibration reducer, the "Vibration reducer u-joint" combination.

Why do you need a vibration reducer in your Chevy? To help eliminate noise, vibration and the harshness that you feel at the wheel. Say you are out cruising, about half an hour into your goodtime you notice your hand starts to feel like you have been running a weed eater all day. This is a good indication that you either don't have a vibration reducer in your steering system; your vibration reducer is worn or in some cases something a little more in depth is the culprit. In any case, you need to check it out and repair the problem to make your vehicle more enjoyable to drive.

The factory style or rag joint has been used for sometime as an OEM vibration reducer. Borgeson offers a full line of splined and DD rag joints to help accommodate your needs and still give your vehicle that stock look. So weather you are replacing the steering column, the steering box or both, Borgeson has the rag-joint for your application. For any technical or ordering information, please call 860-482-8283.

Inline Vibration Reducers

0602sc_suspolystpr_16_z 73/116

In line vibration reducers, when building your steering system and you have the room to accommodate a vibration reducer and there is no angle difference between the two connecting shafts then an in-line vibration reducer is the answer. Measuring 3 ?" in overall length and 1 ?" diameter, this is more compact in width then the rag joint and a much better looking choice.

Vibration reducer u-joint combination. Measuring 4 ?" in overall length, the vibration reducer u-joint performs two functions. It is a vibration reducer, much like the in-line vibration reducer but with the added benefit of a u-joint attached to one end. These are great when used in place of a regular u-joint to give you the added benefit of the vibration reducer. The vibration reducer u-joint combination or "VJ" still offers thirty-five degrees of angle, the same as our standard u-joint. Offered in steel, stainless steel and polished stainless steel, this is a must have when designing a new steering system. For any technical or ordering information, please call 860-482-8283.

BRAKE SYSTEMS

How, What, and Why

0509sc_bkbasics_01_z 77/116

We're all well aware of how important the braking system in our vehicles is. And, we all know what could happen if the brakes fail--the result could be down right disastrous. Unfortunately, we tend to pay much more attention to making our vehicles go fast than we do to stopping fast. For this month's issue we decided to highlight braking systems, as you can probably tell by now. Here I'm going to attempt to layout a bunch of brake basics for you. Who knows, I may have found a tidbit that you were not aware of. For example, did you know that every time you mash that pedal, the hydraulic system exerts as much as 1,000 pounds of hydraulic pressure to each of the four brakes? We all might learn something here after all.

Brakes are essentially energy-conversion devices, which alter the kinetic energy (momentum) of your vehicle into thermal energy (heat). It's this factor that I believe led to the development and popularity of disc brakes--but, I'm getting ahead of myself here. Let's get to some real basic info and then work our way up to specifics.

0509sc_bkbasics_02_z 78/116

BRAKE COMPONENTS
In the brake systems we're familiar with, the master cylinder is usually separately chambered, (one fluid reservoir for the front and one for the rear), and power-assisted to activate both the front and rear brakes. This way, if either fails the other can provide adequate braking power. Such safety systems within the braking system make modern brakes very complex, but much safer than earlier braking systems found on our beloved classic Chevys. Single chamber masters and four-wheel drum brakes aren't going to cut it these days, especially not in performance vehicles. High-performance disc brakes are the way to go. They were originally developed for racing, but are now used on most cars and a disc/drum or disc/disc conversion should be a near-top priority on your classic vehicle upgrade list.

In almost all braking systems, the brake pedal is connected to a "master cylinder" by a pushrod. The master cylinder is connected to small slave cylinders at each wheel by steel brake lines and flexible rubber hoses. The entire hydraulic system is filled with brake fluid, which is forced through the system by pressing on the brake pedal, causing the movement of the master cylinder pistons. The front disc brakes use friction "pads" which are mounted in "calipers." The pads are forced against machined surfaces of a rotating disc called the "rotor." The rear brakes are usually of the "drum" type. In these, the internal expanding brake "shoes" are forced against the inside-machined surface of a rotating drum.

In recent years, brakes have dramatically changed in design. Disc brakes, due to their lighter weight, superior cooling, and better performance are replacing drum types on the rear wheels, as well. As I stated earlier, instead of shoes, which press outward against the inside of a drum, a disc attached to the axle is gripped from either side by friction pads attached to the calipers, just like the ones up front. The greatest advantage of disc brakes all around is that they're essentially "fade" free; that is, repeated application doesn't result in excessively high temperatures developing (as in the case of drums), lowering the stopping power of the brake. Commonplace on newer cars are "anti-lock" brake systems, (ABS) which pulse the hydraulic pressure, preventing the wheels from locking up when the brakes are applied in a panic stop.

0509sc_bkbasics_05_z 79/116

POWER BOOSTERS
Power brake units used on passenger cars are of four general types: vacuum suspended; air suspended; hydraulic booster, and electro-hydraulic booster. Most power brakes use vacuum-suspended units, which contain a large vacuum-powered booster device to provide the added thrust to the typical power brake. Pressure on the brake pedal pushes a rod connected to the pistons of the two master cylinders forward. The pistons begin forcing fluid into the front and rear brake lines. At the same time, the brake-pedal pushrod positions the vacuum-control valve so that it closes the vacuum port and seals off the forward half of the booster unit. The engine vacuum line then draws off the air, creating a low-pressure vacuum chamber. Atmospheric pressure in the control chamber then pushes against the diaphragm, dividing the two chambers, the pressure on the diaphragm, which is locked to the pushrod, forces it forward, supplying even more pressure on the pistons.

0509sc_bkbasics_04_z 80/116

CALIPERS AND ROTORS
At the heart of the modern brake system are the caliper and disc rotor (which rotates with the wheel). When the brakes are applied, the caliper tries to "grab" and stop the rotor. The efficiency of this system is very good, and depends on a few basic factors:
The ability to apply enough clamping force to overcome the rotating rotor. The ability of the pads to maintain adequate friction properties even with the heat generated by continuous application of pressure from the caliper. The ability of the rotor to absorb and dissipate heat. AND the necessary traction from the tires to allow the brake system to be effective. Also, there are different types of calipers. A "fixed" caliper is rigidly secured to the axle assembly and has at least two opposing pistons that force the pads against the disc. A sliding or "floating" caliper has pistons on only one side of the disc. Therefore, when the caliper acts, it must slide or float in order to bring the pad on the opposite side in contact with the disc. Nearly all of the original equipment calipers are of the floating type. In a system with fixed calipers, not only is the mounting much more rigid, but the stiffness of the caliper itself is greatly increased; this manifests itself in enhanced braking performance, pedal feel, and pad wear.

Also, fixed calipers do not suffer the drag (friction) from moving parts common in sliding calipers and are therefore more efficient. These calipers have a much quicker reaction time, which translates to shorter stopping distances as measured from the driver's reaction point.

If we increase the area of the caliper pistons by increasing their diameter, the caliper will apply more clamping force to the pads and rotor, further increasing the braking capacity of the vehicle. Because the hydraulic pressure is constant throughout the system when the brake is applied, the more caliper pistons we add, the more pressure is exerted by the caliper; more pressure or clamping power is more effective in preventing rotation of the rotor.

0509sc_bkbasics_06_z 81/116

ROTORS
The distance from the center of the rotor to its edge (radius) can be thought of as a lever, and the caliper in effect pulls on the lever to slow the vehicle; the bigger the rotor, the longer the lever--the longer the lever the more effective the caliper. It is easy to understand then that larger rotors increase braking capacity. If the rotor is also well ventilated, its ability to dissipate heat is improved, allowing the caliper pads to operate at a lower temperature and tolerate the torture to which they are subjected. When holes are drilled through the rotor and slots cut into the surfaces of the rotor, it provides channels through which the expanding gases can escape, increasing the brake efficiency a step further over a solid rotor. However, these rotor-surface treatments do not automatically guarantee a shorter stopping distance, but they usually can. As mentioned, cross-drilling and slotting is useful when the pads become sufficiently hot to emit gases. Without an escape route, the gases are trapped between the pad and rotor and actually reduce the pad pressure to the rotor (brake fade).

PADS
Different pad compounds offer different friction coefficients and the ability to work well at certain temperature ranges. Most often, a compromise is reached between the friction coefficient and the ability of the compound to operate at the expected temperatures. The higher the friction coefficient of the pad compound, the more grip it has on the rotor, making the brakes more effective.

In the event that the brake system is used to full capacity, even with all of the improvements and the rotor pads are overheated, they will give off gases as a result of the bonding agents in the pad lining that are beginning to burn. The expanding gases from the pad ("out gasing") form a cushion between the pad and the rotor, rapidly decreasing braking effectiveness. This condition is referred to as "brake fade."

Probably the least expensive, most effective upgrade one can perform is a brake pad upgrade. There are as many pad compounds as manufacturers of pads, and each has its particular niche. Brake pads are available in three basic categories: Street, Street / Race combination, and Race Only. Street pads have to be able to work well at low to moderate temperatures because street vehicles are driven cold and under normal circumstances don't generate high temperatures. Usually in this category, the pads work well while cold and their effectiveness decreases as their temperatures increase until the breakdown of the compound bonding agents cause brake fade. Repeated hard brake applications, as in most types of racing, will quickly overheat these pads and render them useless. Combination pads usually incorporate some degree of compromise to incorporate this flexibility of use. For the street they have to work well enough at low temperatures to be safe and must also be competitively functional at moderately high temperatures under racing conditions. Race Only pads do not work cold--period. Do not use Race Only pads on a street vehicle with the idea that "If they are for racing they must be great pads." You will be in for a huge surprise the first time you go to stop.

TIRES
All the brake improvements in the world are not going to help if there is no traction available between the wheel and road. Ultimately, your tires will determine how well your car stops. A brake system of proven efficiency will be most effective with the smallest possible diameter tire. In the same way that the larger rotor offers the caliper a longer lever, the smallest diameter tire offers the a smaller lever. While different (smaller) wheel and tire diameters are frequently an option for racers, most street vehicles are limited to near-standard tire diameters for a variety of reasons. Fortunately, the trend in recent years toward larger diameter rims and low profile tires has opened up many options in the area of big brakes. In many cases, increasing rotor diameter will require an increase in rim diameter to make room for the rotor. Fortunately, low profile tires keep the outside diameter the same or nearly the same as the original equipment. Increasing the rim diameter, therefore, usually has no ill effect on braking. Conversely, modern low profile tires are typically of a higher traction rating (or at least high traction ratings are available) which will aid braking.

Frequently Asked Questions

MASTER CYLINDERS

Q. How can I tell if my master cylinder is bad?
A. When your master cylinder goes bad you will have a very spongy pedal, and if you keep pressure on the brake pedal it will slowly sink to the floor.

Q. What's the advantage of replacing my original single piston master cylinder with a dual piston?
A. Safety. If you brake a line with a dual piston master you will still have half the system available as a backup. With a single piston master you will lose all your brakes.

Q. Should I purchase a new or rebuilt master?
A. Given the opportunity choose the new over the rebuilt. The additional cost of a new master is easily justified by the fact that new cylinders have a much lower failure rate than a rebuilt one.

Q. I purchased a replacement master cylinder and it doesn't look like the original. Can I use it?
A. Probably. Many aftermarket master cylinders have a different casting but internally they are the same. Avoid cheap imports!

Q. How does a disc brake master cylinder differ from a drum brake master?
A. A drum brake master will differ from a disc brake master in two ways: the amount of fluid that a drum brake master moves is less than that moved by a disc master and drum masters have 10-pound residual valves to the drums. If you use a drum master for disc brakes you would move an insufficient volume of fluid and the disc brakes would drag because of the residual valves.

Q. What is the difference between a power brake master and a manual brake master?
A. As a general rule, a power brake master will have a larger bore diameter than a manual brake master. Also, a manual master will have a deep piston hole to accept the manual brake push rod while a power brake master will have a shallow hole.

Q. What bore size and pedal ratio is needed for a manual brake master cylinder?
A. For manual brakes you should always use a master cylinder with a bore size of 1 inch or smaller with a pedal ratio of 6: 1.

Q. I have manual brakes with an extremely hard pedal. Why?
A. Check the bore size of the master, it's probably larger than 1 inch. Also check that your wheel cylinders are not frozen.

Q. Can I use my disc/drum master for four-wheel disc brakes?
A. No. The addition of rear disc brakes requires a true four-wheel disc brake master cylinder which will supply more fluid pressure and volume to the rear calipers.

Q. Why is one chamber in a disc/drum master larger than the other?
A. The master cylinder chamber that feeds the front disc brakes will have its fluid level drop faster than the drum brake chamber because the front pads wear faster, allowing the caliper pistons to extend outward.

Q. Can I use my manual brake master cylinder on a power booster?
A. Yes. However you must be sure that the booster pin length matches the hole depth of the master cylinder pistons.

Q. Can I use my power brake master cylinder for manual brakes?
A. No. The bore size of the power master will probably be too large and the piston hole depth will be too shallow.

Q. How do I increase my pedal ratio when I convert from power to manual brakes?
A. Attach the manual brake push rod 1 inch higher on the pedal than the power brake attachment point.

Q. Do I need to bench bleed my master cylinder before installing it?
A. Yes, always bench bleed before installation.

Coilover Shocks

0602sc_shkpr1_03_z 96/116

VariShock's double-adjustable design (shown) is easier to tune: 256 different settings are attainable simply by rotating two fully accessible, 16-position knobs. All adjustments are made in seconds, without removing or unbolting the VariShock. One knob sets the bump range; the other sets rebound. Both knobs are laser-etched with directional arrows and "plus/minus" symbols that clearly indicate which direction achieves the desired adjustment. Additional arrows etched into the QuickSet 2's base reveal which knob sets bump, and which sets rebound. In the single adjustable QuickSet 1, 14 positions adjust bump and rebound. Repeatability is unprecedented! By controlling the quality of the components, assembling them in-house and dyno-testing every assembly, we can deliver a pair of VariShocks that perform virtually identically throughout the entire range of travel. The spherical-bearing eyes use a COM-8 1/2" bore x 1-1/8" wide high-misalignment bearing with a Teflon liner as standard. The eye has more clearance around the mounting brackets than any other design. The urethane end has up to 350% more urethane material than other brands, for superior load distribution, yet no less clearance around the eye. We use a premium urethane that has much higher load capacity for improved life than the poly bushings. Urethane ends are 11/4" wide and accept 1/2" bolts. A new-design, one-piece lower spring seat does not require a lock nut; it's locked in place by two balllocks that press into the grooves on the reservoir body and easily unlock for adjustment with an Allen wrench. Spring seats accept 2-1/2"-ID coil springs. Chris Alston Chassis Works, 8661 Younger Creek Dr., Dept. SC, Sacramento, CA 95828, 916-388-0288, www.cachassisworks.com.

Eliminator II Rear Frames

0602sc_frame_03_z 105/116

These affordable rear-frame systems bring you all the advantages of our Eliminator II suspension in the economical "back-half" style. These rear frames make the perfect starting point for a higher-technology bracket car or the ultimate Pro Street vehicle. This frame is offered in three styles: 3x2"-box-rail style or two 1-5/8"- round-tube versions. For round-rail cars in which the driver's seat is far back in the body, up against the wheel tub, use Model 7130. In this frame, the 4-link front mount is even with the main hoop. For longer-wheelbase cars, which position the driver's seat considerably forward of the rear wheel tubs (6" to 12"), use Model 7131. In this frame, the 4-link front mounts attach to bent crossmembers that extend behind the main hoop. The 3x2"-box-rail version will fit most vehicles and is easier to install. All three frames require the use of a Chassisworks 14-point cage for the necessary rigidity and extra tubes to complete your frame. You will also need 7"-travel coil-overs.

Classic Camaro Subframes

0602sc_frame_09_z 111/116

You wanna build a G-machine with your '67-'69 Camaro but tire size and ground clearance are limited. Dropping some weight would be great, and the original front suspension design doesn't do a very good job of planting the tires either. Fatman's has designed complete replacement subframe, which provides vastly improved geometry, with approximately 2-inches more ground clearance at the front crossmember, a 2-inch overall narrower track width, and a super low stance. The unit bolts to the floor and cowl as original, and provides mount holes for the core support, bumper, and fuel and brake lines. We also include an adapter kit to allow use of your original '69-style disc brakes and hoses. Your original engine mounts will swap over. Tubular control arms, dropped spindles with brake adapters, rebuilt power rack and stainless steel hose kit, steering connection kit and sway bar are included. You'll want to plan on some light fabrication work on brake lines and steering hookup, but we've attempted to put together a very complete kit with all the little details needed to finish the job.

0602sc_frame_10_z 112/116

S&W Race Cars all new, extreme-duty, a-arm front frame & suspension package is specifically designed to withstand the loads applied by both heavy weight E.T. race cars and even the heaviest Pro/Streeter.

This frame features 2" x 3" mandrel formed frame rails made from heavy duty .120" wall tubing. All brackets are precision, waterjet cut from 3/16" steel. Also included in each package is a floor x-brace kit for added support. More support comes from a pair of front subframe supports, to tie into your roll cage and a pair of shock support tubes (not shown in photo). This frame package uses easy to find Mustang II spindles (not included) or S&W fabricated spindles, Mustang II rack & pinion and QA1 coil over shocks. Tubular a-arm packages are powder-coated for a durable and attractive finish. In addition to the weight savings, you get the benefits of a fully adjustable, "zero-bump-steer" front suspension with coil over shocks for the ultimate in adjustability and consistency. The rack and pinion steering eliminates the sloppy original steering box and offers added header clearance by moving all the steering components forward of the motor. This frame rail and crossmember package, features all brackets completely fixture welded to the frame rails, insuring proper alignment of all critical suspension mounts. The rack & pinion crossmember is cut to width and the floor support tubes are notched and cut for easy installation. Shipping these components separately makes the entire package UPS-able, saving you money on freight charges. S&W Race Cars, 11 Mennonite Church Rd., Dept.
