The Bilstein B16 (PSS10) suspension kit for 1989 Porsche 911 Carrera 4 is a direct-fit front and rear system that uses monotube dampers and springs tuned for this Carrera 4 application to improve handling and allow ride-height adjustment. The ten-stage manual damper adjusts rebound and compression in fine steps for adaptable control. Threaded, zinc-coated bodies allow approximately 30–50mm lowering; Triple-C corrosion protection, German manufacture, and Nürburgring‑tested engineering support durable, tunable performance.
