Bilstein B8 Performance Plus is a front strut assembly built as a performance upgrade over the OE damper and engineered to pair with aftermarket lowering springs. It uses a twin-tube design with application-specific valving tuned to the Boxster chassis for sharper handling and body control. Each unit is tested to meet or exceed OE standards and carries Bilstein gas-pressure construction for consistent damping.
