BC Racing BMW 128ti F40 DS Series 1 Way Adjustment Coilover

Overview

BC Racing’s new proprietary digressive piston design offers increased damping force at low piston velocities (0-50mm/s) while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g., roll, pitch, dive, and quick weight transitions on technical road courses. BC Racing's DS Coilover system is built with digressive valving offering the same great benefits of the BR Type model and is considered a perfect choice for those who are looking for track biased coilovers. The digressive piston design gives a non linear damping curve which allows higher low speed damping to be run to control body roll through cornering, acceleration and braking whilst providing reduced high speed damping to allow the wheel to travel whilst running kerbs to prevent the impact from transmitting fully into the shell so retaining car balance.
