The Bilstein B16 (PSS9) is a direct-fit coilover suspension system for the Porsche Boxster and Cayman (987), offering ride-height adjustability and 9-stage manual damping. Each click simultaneously adjusts rebound and compression on the monotube dampers, which are matched to application-tuned springs. The threaded, zinc-coated steel body resists corrosion and allows roughly 30-50mm of lowering. Made in Germany and developed under motorsport conditions at the Nürburgring.
