This is a complete bolt-on front coilover kit for 84-87 C4 Corvettes. The kit features premium all-aluminum JRI coilover shocks that are built specifically to After Dark Speed specifications based on real world testing and competition results with the After Dark Speed C4 Corvette autocross car. This kit also includes specific springs that are optimized for this kit and autocross/track use. Specific custom spring rates can be requested.
The kit is optimized around a 1″ to 1-1/2″ drop from stock and exact height is easily fine-tuned with the coilover adjuster nuts. The coilover kit makes spring changes very easy so you can tune the ride and balance of the car. There is also a large selection of spring rates available. The factory C4 composite leaf springs are only available in a very limited number of rates and some are difficult to find now. The default included spring rates are based on what the After Dark Speed C4 autocross car is running.
The front coilover kit also includes the front sway bar heavy-duty, hi-performance end-link kit for all 84-87 Corvettes which uses HD chromoly aircraft-grade heim joints with teflon liners. It works with all 84-87 C4 OEM front sway bars and eliminates all rubber bushings by using special CNC machined inserts and adapter brackets.
84-87 C4 Front Sway Bar Relocation Kit is required for clearance and available from After Dark Speed. HD front endlink is not required since it is included with the front coilover kit.
Select non-adjustable, single-adjustable, or double-adjustable versions (double-adjustable is recommended for autocross and competition use).
All parts are powder coated, zinc plated, and black anodized for corrosion resistance.
