Coilovers

A coilover (short for "coil-over shock absorber") is a high-performance suspension component that integrates a coil spring directly over a shock absorber into a single, compact unit. While they function similarly to standard struts, coilovers are primarily designed for adjustability and precision handling. They are a favorite among car enthusiasts and racers because they allow for fine-tuning a vehicle's ride height, stiffness, and damping characteristics to suit specific driving conditions. The most distinctive feature of a coilover is the threaded shock body and adjustable spring perch. By rotating a threaded collar up or down the shock body, a driver can manually raise or lower the car's ride height, which lowers the center of gravity for better cornering. Many high-end coilovers also feature adjustment knobs on the top or bottom that allow you to change the "valving" (stiffness) of the shock, switching from a soft, comfortable street ride to a stiff, responsive track setting in seconds. Structurally, coilovers are built to be more robust than factory suspension, often featuring high-grade aluminum or stainless steel bodies and specialized linear-rate springs. Because they replace the entire factory spring and shock assembly, they provide a more direct connection between the chassis and the road, significantly reducing body roll and "dive" during hard braking. While they offer superior performance, they generally provide a firmer ride than standard shocks, making them a trade-off between extreme handling and everyday plushness.
