A coilover suspension system combines a coil spring and shock absorber into one unit. This system replaces the regular factory suspension that usually separates the spring from the shock. Coilovers are used to improve a vehicle's handling, stability, and ride height adjustability.
The main benefit of coilovers is that they let you adjust the ride height of your car. This is done by turning a collar on the threaded body of the coilover. Lowering the ride height can improve cornering and give your car a more aggressive look. Raising the ride height can give you better clearance for rough roads or larger wheels.
Some coilovers also allow for damping adjustment, which controls how stiff or soft the suspension feels. This means you can tune your suspension for comfort during daily driving or firm it up for better control on the track.
Popular brands like BC Racing coilovers offer both ride height and damping adjustment, making them ideal for street and performance use. Whether you’re building a track car or just want a better ride, coilover suspension gives you more control than stock setups.
