Bilstein B4 Rear Damper for BMW F30 F31 F32 F33 F36 M Sport | Part No. 19-220093

Bring back tight, confident road manners with this factory-spec rear damper designed for BMW F3x M Sport chassis. The Bilstein B4 uses proven gas pressure technology to keep your back axle planted, reduce float, and deliver the calm, composed ride quality your BMW should have. It is a direct-fit unit for rear wheel drive models and retains OEM comfort with crisp control on B-roads and motorways alike.

We fit these in-house and run them on our own cars. Customer feedback is consistently positive for grip, stability and everyday refinement. If your car crashes over bumps, feels unsettled, or shows uneven tyre wear, refreshing the rear with B4s transforms confidence without making the ride harsh.
