BC Racing's DS Coilover system, featuring digressive valving, inherits the excellent qualities of the BR Type model, making it an ideal option for individuals seeking coilovers with a track-oriented bias. The digressive piston design introduces a non-linear damping curve, enabling increased low-speed damping to manage body roll during cornering, acceleration, and braking. Simultaneously, it reduces high-speed damping to permit wheel travel when navigating over curbs, preventing the full impact from transferring into the vehicle's structure and preserving overall car balance.
