The Bilstein B16 (PSS9) suspension kit for the 2002 Audi A4 Base is a direct‑fit coilover that swaps OE dampers for monotube units matched with tuned springs to improve handling and control. The 9‑stage manual damping system adjusts both rebound and compression to better suit road and spirited driving. A zinc‑coated threaded body allows about 30–50mm lowering, features Triple‑C corrosion resistance, quick damping adjustment, and German engineering refined on the Nürburgring.
