The Bilstein B8 SP is a performance strut assembly built to pair with aftermarket lowering springs or factory sport suspensions on the F55/F56 Mini Cooper. It uses application-specific valving and a gas-pressure twin-tube design with a shorter, firmer stroke than the OE damper to control a lowered ride height while keeping daily comfort. This unit is the front left (driver side) strut and fits Cooper Base, S, and John Cooper Works models without electronic damper control.
