Why spend all day at the track dialing in your suspension when you should be on the track enjoying the experience. Damper and camber adjustments should not be a definitive factor, nor should you spend all day adjusting your suspension settings at the track. Drive to the track, on the track and drive home in comfort. Enjoy driving again with the RS-R coilovers.

Quality and Detail

The RS-R coilovers are all Monotube hand assembled systems specifically designed to improve ride quality, performance, and comfort. Utilizing components such as; laser cut upper mounts, hand welded lower brackets, vehicle specific valving, are all assembled by hand to ensure quality and detail.

Urethane Bushing Technology

Utilizing Urethane bushing instead of bearing to reduce excessive vibrations from everyday driving, as well as minimizing noises from suspension movements.

The Silent Roller Bearings

On MacPherson type suspension, as the suspension rotates along with the steering wheel, the coil springs may be prone to twisting. RS-R suspension utilizes roller bearings to eliminate spring twist noise.

Comfort and Adjustment

Rubber padding is utilized to help eliminate potential noise from suspension movements. Damper adjustment dials are up to 36 way adjustable to tune the shocks compression and rebound to each individuals needs for almost any driving condition.

Damping Adjustment
