It maintains the construction of the BR and DS series, with a monotube shock absorber and digressive piston, and adds 30 adjustable compression clicks from the reservoir plus another 30 for rebound from the top of the shock. This independence is particularly advantageous when entering a corner: compression determines how the front end loads under braking, and rebound determines the rate at which it recovers when the pedal is released.\u003c\/p\u003e\u003cp\u003eComplete kit for all four wheels of the BMW 3 Series F31 RWD\/xDrive (12-19) (5-bolt Ftm).
