It maintains the construction of the BR and DS series, with a monotube shock absorber and digressive piston, and adds 30 clicks of compression adjustable from the reservoir plus another 30 of rebound from the top of the shock absorber. This independence is especially useful when entering corners: compression determines how the front end loads under braking, and rebound determines the rate at which it recovers when releasing the pedal.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW M3 F80 \/ M4 F82 RWD (14-20), 5-bolt top mount.
