If anything confounds us it is enthusiasts who put the cart before the horse. They build all kinds of power into a vintage muscle car and save brakes and suspension for last when it really should be the other way around. Brakes and suspension are safety items that should come first when you’re building a fast Chevy muscle car. You want control of all that power and you certainly want to be able to stop when the fun is over.

Performance Online (POL) has affordable solutions for enthusiasts who want more from their vintage and late-model Chevy powerhouses. The key to having it all is how you spend your money getting there. You want the best handling and braking you can get without selling off the farm. POL has an extensive, and affordable, product line that enables you to build performance into your ride without spending a lot of money.

Nothing is more paramount than your Chevy’s brake system. A good brake system can make the difference between avoiding an accident and having one. The best accident is the one you never have. Good brakes also helps a car’s handling since they inspire confidence and allow you to dive a bit deeper into a curve.

Although aftermarket disc brake systems for classic Chevys have been available for a long time now, there are still plenty of classics out there with four-wheel manual drum brakes or, like our first-gen Camaro, sporting power front disc/rear drum brakes, but lacking the braking performance we’d like. We want this thing to stop after a wide-open throttle blast.

Of course, roads often have curves and nothing beats slicing through them in a Chevy with a capable suspension. Also, nothing is scarier than a classic Chevy with unpredictable and sketchy road manners. Our 1968 Camaro fell into this category. The stock suspension was well worn, which added more problems to the performance equation. So along with brakes we also decided to tackle the suspension and any other issues we found along the way.

We’re working with a small-block ’68 Camaro sporting power front disc brakes with rear drums as a chaser and a bone stock suspension. Because we’re on a budget, we’ve opted for a freshening up, with a new power booster and master cylinder, along with rear disc brakes to help make our Camaro safer. We also went with updated suspension parts to help the Camaro ride and handle better than it did even when brand-new. POL has everything we’re going to need to get the Camaro’s performance where it needs to be for safe driving and precision stopping. We also decided the old tires weren’t helping in the handling department and the 16-inch rims were giving the Camaro a dated look so budget-friendly rollers and fresh rubber were put on the to-do list as well.

1. Our ’68 Camaro sports its original suspension system with a stock ride height. We’re going to change all of that with a complete Performance Online (POL) suspension system, which will lower the ride height; improve the handling; and give our first-gen Camaro a down-low, road-hugger stance.

2. These 1967-’69 Chevrolet Camaro tubular control arms from POL are powdercoated for extreme durability and good looks. They include bumpstops and have improved ball joint clearances. These guys improve frontend geometry and, as a result, handling. They work with stock coil springs or coilover shocks. The lower control arms feature a dropped spring pocket.

3. Stubborn ball joints can be motivated with heat. Do not overdo it with excessive heat, which can damage the spindle or at the least weaken it. Once hot, whack the spindle with a five-pound sledge, which should jar the ball stud loose. Of course, a ball joint fork would work as well.

4. The upper control arm attachment point is loosened as shown. Take an accounting of the number of alignment shims and where they are positioned. We had plenty of clearance, but sometimes this part can be challenging if headers are involved.

5. We could then remove the upper control arm. Always recycle steel suspension components such as upper control arms. Hey, a few bucks from the scrap guy is better than nothing.

007 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 7/32

6. Place some sort of support beneath the ball joint of the lower control arm. The shocks are removed next using a 5/8-inch deep well socket on tip and 9/16-inch bottom. Front shock absorbers come out through the bottom once the fasteners are removed. Slowly lower the support under the ball joint to release the tension on the coil spring until it can be safely removed. Always pay very close attention to coil springs under pressure, which can cause serious injuries if the proper precautions are not taken.

7. POL tubular lower control arms are installed like this. Be advised that these bushings can be very stubborn, making it hard to seat the arm. This is normal. The bushings should be lubricated with the provided lubricant. Always use protective gloves when using this stuff since it tends to get everywhere and make a mess of things.

009 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 9/32

8. The new POL lowering coil spring is installed next. We’re using a jack stand for lower control arm support. In your home garage, safely position your Camaro on jack stands and use a floor jack for control arm support.

010 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 10/32

9. The POL tubular upper control arm is installed next. Be sure to use the same complement of shims as used on the factory arms. Tighten the fasteners to GM specifications. We will still need to get a full alignment, but this should get us close enough to be able to drive to the shop.

011 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 11/32

10. POL provided new tie-rod ends and billet adjustment sleeves for easy adjustment. We’ve taken the original tie-rod ends and used them as a reference. The new sleeves are considerably stronger than the stamped steel stockers.

012 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 12/32

11. Also included in the stack of parts from POL was a heavy-duty front sway bar and polyurethane bushings to stiffen up the handling and reduce body roll.

013 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 13/32

12. The old shocks were pretty time-tired and as a bonus the bushings were dried-out, cracked, and not really bringing anything to the handling party.

014 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 14/32

13. POL got us into new rear suspension components, including multileaf springs, Western Chassis gas shocks, and shock relocation brackets (top and bottom). The kit also included the necessary hardware and new U-bolts.

015 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 15/32

14. The upper shock mount crossbrace bolted up under the Camaro between the factory framerails as shown. In addition to giving the shocks a new place to mount, the bar also adds a bit more chassis stiffness. This bar eliminates the stock upper shock mounts.

016 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 16/32

15. Three bolts secure the leaf spring eyelets in front, which makes them easier to remove than most applications. It’s best to do one complete leaf spring at a time, supporting that side while making the switch. This is the front mounting plate, which we reused. Like the rest of the old the suspension, the leaf spring bushings were pretty shot.

017 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 17/32

16. The new POL multileafs are installed as shown. Joel Rode of Hot Rod Specialties has lubed the pivot points with chassis grease. Ride height depends on which leaf springs you have ordered. Lower is better as long as you don’t get into tire and wheelwell interference.

018 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 18/32

17. The bottom shock and leaf spring mounts are installed using new U-bolts. U-bolt length is an important consideration. Keep length conservative at no more than 1-inch of stud exposed. We left extra just in case we decide to drop the rear down a bit more with some lowering blocks.

019 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 19/32

18. While under the Camaro to do the suspension upgrades we noticed the front subframe bushings were shot. How shot? Well, let’s just say they weren’t doing much besides taking up space. The answer was to grab a set of better polyurethane pieces from Energy Suspension.

020 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 20/32

19. The new bushings were pretty easy to install. To keep the subframe aligned we did the rears first and then the pair near the firewall and finally the ones on the front core support.

021 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 21/32

20. Our small-block Camaro is fitted with box-stock single-piston front disc brakes, which do an adequate job of stopping in daily driving. We’re going to fit these binders with slotted and vented POL rotors in an effort to improve performance. As a bonus, the zinc washed rotors look a ton better.

022 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 22/32

21. POL has provided us with a new power booster, master cylinder, and disc brake distribution block to fully complement our upgraded and refreshed braking system. These components are all drop-in replacements without the need for any modifications.

023 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 23/32

22. The power brake booster pedal pushrod is secured here at the brake light switch and pedal. Pull the pin and the booster is disconnected.

024 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 24/32

23. Joel removes the original power brake booster. If this was a full restoration we would have had this one rebuilt.

025 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 25/32

24. The POL power brake booster slips right into place without modifications or frustration. Four pedal support studs protruding through the firewall support the booster. Once bolted to the firewall we went back under the dash and attached the clevis to the brake pedal.

026 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 26/32

25. Joel performs a bench bleed before installing the dual master cylinder from POL. This ensures the master is free of air prior to installation. It keeps us from introducing a bunch of air into the brake hydraulic system. Joel installs the POL master cylinder, which offers greater capacity than original equipment. The brake proportioning/pressure differential valve is a direct replacement for original equipment and is valved for rear disc brakes.

027 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 27/32

26. This Camaro has a 10-bolt differential. You have to pull the cover and pop the C-clips in order to remove the axleshafts so that the drum brake assembly can be removed. This is the best time to replace axle bearings and seals.

028 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 28/32

27. The original axles were badly worn and if we had kept them the seals would have certainly leaked. So we installed a pair of affordable Summit axles to complement our rear disc brake upgrade. The disc brake caliper bracket has been installed using a thread locker and proper bolt torque.

029 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 29/32

28. The POL slotted and vented rear disc brake rotors are installed for the same reason we used them in front. Slotted and vented rotors get rid of heat better and allow for an improved pad-to-rotor relationship. In short, they offer better braking while being better looking.

030 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 30/32

29. We have secured the rear brake calipers and installed the parking brake cables. A complete brake system bleed begins at the right-rear caliper, then the left-rear. The right-front is next, and finally the left-front, which is closest to the master cylinder. Expect to go through this routine two or three times to get all the air out. With each bleeding exercise and a good shakedown with hard braking, the pedal will become harder and more predictable.

031 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 31/32

30. We also decided to up the handling and looks dramatically with a set of new wheels and tires. The wallet friendly aluminum wheels are from American Legend. These are their Cruiser wheels, which offer a modern diameter of 18-inches while keeping the vintage look of an original Rally wheel. They came with flat “dog dish” center caps, but we opted for some short disc brake caps from Classic Industries. Given the low-profile tires we did add a set of 1-inch lowering blocks to the rear to get the stance right.

032 Performance Online 1967 1981 Camaro Suspension American Legend Falken 615K 32/32

31. For tires we went with 235/40R18 front and 275/35R18 rear Falken RT615K tires. The 200 treadwear tires will add a lot to the Camaro’s grip and still wear well on the street. The 18-inch American Legend wheels (18x8 front and 18x9 rear) and modern tires really updated our ’68 Camaro and were a great complement to our fresh POL suspension system. Now to find and alignment shop and then a nice curvy road.
