Part 2: Manufacturers K-V
in our last issue, we brought you a plethora of manufacturers promising to improve your Corvette's ride and handling with the latest in shocks, springs, control arms, antisway bars, and bushings. This month, we bring you another sampling of suspension specialists, each one ready to provide you with the mods you need to enhance the agility of your Corvette.

Because choosing the right suspension parts is a largely subjective endeavor, we didn't favor one of these manufacturers over the others. Instead, we listed them all (half last month and half this month) and allowed them to state their case. All that's left is for you to decide is which one's right for your Corvette.

Performance Suspension Technology (PST)
(800) 226-4101
www.p-s-t.com

Brief Description
PST's frontend kits, G-Max sway bars, and Ground Zero coil and leaf springs are specifically engineered to work together as a complete system. Our high-performance Polygraphite frontend kits eliminate steering slop and play caused by old, worn components and upgrade the Corvette's performance to unmatched levels.

G-Max sway bars feature larger diameters and reduce body roll for flat, fast cornering. A variety of different sizes are available to accommodate street, strip, and autocross applications.

Ground Zero coil and leaf springs are the perfect way to restore new-car stance and performance, or upgrade performance far beyond stock levels. Mileage, age, corrosion, and hard driving all contribute to weak, sagging-and the eventual failure of-springs.

Trademark Features
Polygraphite is a high-performance, graphite-impregnated polyurethane bushing designed for street-, strip-, and track-driven cars. Polygraphite bushings feature near-zero deflection, the superior handling characteristics of polyurethane, and the quiet, lubricating properties of graphite.

PST has been a leader in muscle-car suspension for more than 25 years and warranties all products against defects in material and workmanship for as long as you own the vehicle. Shipping and handling is always free in the Continental U.S.

Quote From Company
"PST is a one-stop solution for all of your suspension needs. We have thousands of satisfied Corvette owners from each generation who swear by our proven Polygraphite system. Give us a call and get your new, improved Corvette back on the road today!"

QA1 Precision Products, Inc.
(800) 721-7761
www.qa1.net

Brief Description
QA1 offers a wide range of high-performance suspension components for both stock and custom Corvette applications. QA1's Stocker Star single- and double-adjustable shock absorbers bolt directly into the stock location on '63-'08 models. The QA1 Pro Coil system, including shocks and springs, improves ride control and offers height adjustability for '63-'82 Corvettes. For customized chassis or rearends, QA1 offers Proma Star single- and double-adjustable shocks. These shocks are available in multiple lengths and mounting configurations to fit custom needs.

QA1's Pro-Street and Pro-Drag systems utilize Proma Star shocks with specialized springs to update the rear of the car to a completely adjustable coilover setup. In addition, QA1 offers a huge selection of springs in multiple lengths and rates. For the hard-core builder, QA1 also has the largest selection of rod ends, spherical bearings, and linkages.

Trademark Features
Every aluminum QA1 shock is 100 percent hand built, dyno tested, and serialized at QA1's Minnesota facility. QA1 single-adjustable shocks control both the compression and rebound simultaneously, allowing total suspension control in one easy-to-reach location without removing the shock from the car. QA1 double-adjustable shocks offer truly independent compression and rebound control. With two knobs-one each for compression and rebound-they provide 576 valving combinations for total suspension control. For drag-oriented cars, QA1 developed the "R" series, which has a firm compression and a wide range of rebound for the ultimate in weight transfer.

Speed Direct
(888) 425-2776
www.speeddirect.com

Brief Description
SpeedDirect offers complete suspension packages for '63-'82 Corvettes, including front and rear coilover-spring conversions, aluminum control arms, upgraded sway bars, and rack-and-pinion steering. Shark Bite coilover kits replace the monoleaf springs with truly independent front and rear coilovers. These kits boast adjustable shock valving and offer the ability to tune ride height with the turn of a wrench. We also have a variety of spring rates to choose from, allowing you maximum tuning ability.

Our aluminum control arms offer lighter weight, an improved roll center, and greater camber gain, for a better-handling car with more cornering ability. Larger sway bars help the car stay under control by limiting the amount of body roll. Add all these together (plus steering and brake options), and your old classic will finally handle like a new Corvette!

Trademark Features
Our Shark Bite rear coilover suspension for '63-'79 Corvettes is of particular interest, as it uses a race-inspired rocker-arm setup along with the coilovers. This setup completely replaces the bouncy transverse leaf spring with lifelong-rebuildable aluminum shocks. These kits are lighter than the stock suspension and keep all the loads focused where they were intended to be from the factory. One other highlight is that all of SpeedDirect's kits bolt directly into place using the existing mounting locations-no drilling, cutting, or modifying required.

Quote from Company
"SpeedDirect manufactures Corvette steering and suspension components designed to bring modern precision, control, and handling to your classic Corvette."

Brief Description
Tokico Blues are the choice for performance enthusiasts looking for the best in overall handling and ride quality.

Tokico offers a limited lifetime warranty on our products, so you can drive your Vette with confidence.
