RS-R Black-I Coilovers - 01-06 Lexus LS430
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.
