Product Details
These coilovers use a monotube design for consistent damping. You can adjust the rebound, low-speed compression, and high-speed compression separately. This lets you dial in exactly how the car handles bumps and body roll. The kit also includes camber-adjustable front top mounts and solid rear top mounts to give you more control over your alignment.
