RS-R Black-i Coilovers

The Black*i coilover system from RSR has been developed based on a completely different concept from coilovers in the past. Ultra-short stroke shock assembly is used to accommodate the low height setting. The damping force and spring rate is carefully selected for an optimal ride quality. as such, the vehicle is able to be lowered a lot more than any other coilover while keeping a comfortable ride quality.

Coilovers are supposed to function a specific way. The ride height, preload, valving, and spring rates should all work together to provide a specific type of ride. Taking them out of its recommended range causes imbalance and undesired ride quality, especially when you want the car to be low, extremely low. That's where the RS*R Black-i comes in. Not only is it made to allow you to lower your car to levels most coilovers are incapable of, but they have been specifically engineered to do so, in their valving, spring preload, and spring rate. Looking good does not need to sacrifice ride quality or even performance any longer. Look good and have an enjoyable ride with it.

Recommended for the following users:

  • Want to enjoy the super low stance
  • Want to individualize the vehicle with a custom look
  • Want to have the sharp handling responsiveness
  • Suspension with the ability to go super low

RS-R Black-i Coilovers Technology

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.

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

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. 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.

If desired, the upper mounts on select vehicles can add 1.5 degree of camber from the preset setting by unbolting the upper mount and rotating the plate 180 degrees. (for more precise control of camber, adjustable camber plates are available for select models)
