As good as the C5 Z06 suspension is from the factory, there's always room for improvement. Be sure to balance track grip against on-road comfort when making your selections.

Part 1: Manufacturers A-K
Do you feel like you're spinning your wheels looking for the best suspension parts for your Corvette? If so, you're not alone. The sophisticated world of shocks, struts, springs, sway bars, bushings, and other apparatus can be difficult to navigate, especially if your goal is to pick the perfect underpinnings without breaking the bank.

Our official guide to Corvette suspension kits and components will help you select the suspension parts best suited to your car-and your budget. By the time you're done reading, you'll know which of these manufacturers will help you steer with certainty, corner with confidence, track with tenacity, or just improve the daily ride and handling of your street machine. And if you're a drag racer, we'll help you choose the right components to propel your Corvette through the quarter-mile as quickly and consistently as possible.

Because choosing a suspension system is based upon a number of variables-such as vehicle age, weight, horsepower, and intended usage-we didn't favor one of these manufacturers over another. Instead, we listed them all (half this month and half next month, due to space limitations) and allowed them to state their case. All that's left for you to decide is which one is right for your Corvette.

Brief Description
Bilstein offers a complete selection of replacement and upgrade shocks and struts for all generations of Corvette. Many Corvettes came with Bilstein shocks as original equipment.

Vemp_0910_02_z Corvette_suspension_kits Shocks 3/15

Trademark Features
Ride, handling, and control are what a shock or strut provides. Compromise in one area may create a problem in another. Bilstein's unique high-pressure monotube design eliminates any compromise. The rising-rate valving of the Bilstein shock absorber provides the necessary damping to react quicker to road conditions without sacrificing ride comfort. This combination of valving and high-pressure nitrogen gas keeps the tires in constant contact with the road, helping to ensure the highest level of vehicle control.

Unlike other manufacturers which provide a minimum selection of shocks to cover a broad range of applications, Bilstein shocks and struts are built for each specific application. Our engineers take into account everything from external dimensions to internal valving, mounting hardware to the weight and type of vehicle, and intended use.

Quote From Company
"Many Corvette owners have reported to us they are pleasantly surprised when running Bilstein shocks and struts, as the handling, cornering, tire contact, and ride have significantly enhanced the Corvette experience. Bilstein also offers a personable tech department that will help you choose the perfect shock for your application, including custom fitments."

Vemp_0910_03_z Corvette_suspension_kits Coilovers 4/15

Brief Description
DRM offers a full line of suspension kits, components, and installations to suit individual Corvette suspension needs. DRM's '89-'09 Xtra-Grip suspension kit is a coilover-shock conversion that completely removes the leaf springs and the "crosstalk" associated with them. DRM also offers a full range of Bilstein Sport shocks, including our popular C6Z application. Mono-ball control-arm bushing kits completely remove all the unwanted play in the Corvette suspension, while custom-made DRM chassis-stiffener bars significantly reduce chassis flex and increase cornering capabilities and maneuverability. DRM also offers high-performance sway bars for '89-'09 Corvettes.

All of the above kits and parts are available by mail order or with DRM expert installation, which includes corner weighting and alignment for track and street use.

Trademark Features
DRM has chosen high-quality, durable components to create top-of-the-line, dependable suspension-kit packages. All of DRM's coilover and sport shock kits start from Bilstein shock absorbers. DRM also employs Hyperco springs, which have proven to be consistent, even after years of harsh racing use.

If the shocks and springs are the meat and potatoes of DRM's Xtra-grip kit, then the mounts and valving are the dessert. DRM incorporates aircraft-quality materials in the construction of custom mounts. They're designed to offer a full range of motion and quiet operation, and are made in the USA. The valving in our suspension kits has been bred from on-track, street, and skidpad testing to provide a balanced, confidence-inspiring driving experience. This, in conjunction with Bilstein's rising-rate, digressive, working piston, eliminates the need for adjustable shocks. DRM has combined these quality components together to produce a kit that transforms the handling of your Corvette.

Quote From Company
"DRM has been providing 'race-car performance for the street' since 1991, with racing roots back to 1970. All suspension kits have been tested and proven on the street and track by professional engineers and drivers. Experience, quality, and excellent customer service make DRM the choice for your Corvette suspension needs."

Dragvette Products
(877) 422-0943

Vemp_0910_04_z Corvette_suspension_kits 6_link_suspension_system 5/15

Brief Description
The Dragvette Suspension System changes the geometry of the '63-'82 Corvette by repositioning the mounting location of the lower strut bar and adding a top strut bar of equal length. This allows you to set your camber at zero, keeping the tire perfectly straight up and down throughout the range of your suspension travel. This makes for a larger tire contact area that optimizes traction under any conditions. The top link also supports the Corvette's weight (the stock configuration places the weight on the differential side yoke); this takes stress off of one of the weakest components in the Corvette's suspension. The result is awesome traction and greater parts reliability.

Trademark Features
All parts are CNC machined. The Heim joints are the strongest available units with Teflon-lined bearing surfaces, the cadmium-plated strut tubes are heavy walled, and all the bolts are Grade 8. All washers are stainless steel, and aluminum is used for weight reduction whenever possible. The construction includes two pairs of safety loops and a cover girdle for added strength.

Quote From Company
"A Dragvette 6-Link Suspension System will make your Corvette a triple threat with great street manners, awesome autocross handling, and brutal bite at the dragstrip."

Global West Suspension
(877) 470-2975

Vemp_0910_09_z Corvette_suspension_kits A_arm_component 10/15

Brief DescriptionGlobal West manufactures several components for Corvettes. We are the original designers of Del-a-lum bushings, which are a direct replacement on the stock control arms and carry a lifetime warranty for the original owner. We use these bushings for street, road-racing, drag-racing, and autocross applications.

We also have tubular control arms for '63-'82 Corvettes, which improve the original geometry. These arms provide additional caster, dramatically enhancing corner-entry and straight-line stability. Tubular rear swing arms and adjustable strut rods are also available, rounding out the suspension system. These arms accept the standard hub assemblies and mounting tabs. Our race-version rear swing arm uses a spherical bearing, rather than a bushing, for mounting on the frame. The bearing removes swing-arm bind from the equation, making chassis diagnosis easier.

Trademark Features
Our features include the original, U.S.-made Del-a-lum bushing; a limited lifetime warranty to the original purchaser; and full lubrication, so there are no squeaks. Our G-Plus (Geometry Plus) control arms change your Corvette's suspension geometry without modifying the frame. The angles and new alignment settings are derived from years of building and setting up race cars. Each control arm features a bumpstop to protect the ball joints from over-travel, gussets at load-carrying points, heli-arc welding at critical points, proper-size tubing for carrying extreme loads, and a powdercoat finish for long-lasting protection. Del-a-lum bushings are standard.

Quote From Company
"Global West Suspension builds products that look great and perform as stated. Our racing knowledge and background can be a successful tool for the Corvette enthusiast. Contact Global West and check out our website for more information."
