Coilover suspension is a type of vehicle suspension system that combines a coil spring and a shock absorber into a single unit. This design allows for adjustable ride height and damping, enabling drivers to customize their vehicle's handling and comfort. Coilovers are popular in both street and racing applications due to their versatility and performance benefits. The main components of a coilover include the coil spring, which supports the vehicle's weight, and the shock absorber, which controls the movement of the suspension. Many enthusiasts choose coilover kits to improve their car's handling characteristics and achieve a lower stance, enhancing both aesthetics and performance.
