    QA1's Rear Proma Star Pro Coil System converts the Corvette leaf spring suspension to coil-over shocks for improved handling, tunability and ride quality, with quick and easy ride height adjustment. The double adjustable valving independently tunes compression and rebound. Base model cars can be lowered about 1 to 2 inches and Z06 models about 0.5 to 1.5 inches. The coil-overs install with basic hand tools using factory mounting locations and do not require a toe link relocation kit. Models with electronic ride control require Real Time Damping simulators. The shocks are made in the USA, serialized, dyno tested and eligible for a limited lifetime warranty.
