?What is A Coilover?

Coilover is the abbreviation of "coil shock absorber" or "coil spring over the shock ". Coilovers are simply springs/coils that are placed on the shock absorber. The shock absorber is where the damping works. Some coilovers have damping adjustments (compression and rebound) that change their stiffness and can adjust the ride height, giving you the freedom to lower your car for the sporty lowered look. Lowering your car will also improve handling and reduce body roll.
