Bilstein B8 Performance Plus Rear Shock Absorber - BMW F10/F06/F12/F13 2011-2019

B8 Performance Plus is Bilstein's firmer, application-valved damper for cars sitting on aftermarket lowering springs or a factory sport suspension, where a standard damper is working outside the travel it was designed for. The monotube construction separates gas from oil so damping stays consistent as heat builds during hard driving, and the valve settings are chosen per vehicle to tighten body control and steering response without making the ride brittle. Each shock is tested to meet or exceed OE standards and is sold individually, so the rear axle needs two.
