BC RACING COILOVERS DS SERIES - BMW 4 SERIES F83 M4 CABRIO 14-20 (5-BOLT TOP MOUNT)The BC Racing DS Series is built around digressive valving, offering similar benefits to the BR Series but with a stronger focus on track performance. The digressive piston design delivers a non linear damping curve, allowing higher low speed damping to control body roll during cornering, braking, and acceleration, while reducing high speed damping to let the suspension travel freely over kerbs and rough sections without unsettling the chassis.
