The Bilstein B14 (PSS) performance suspension kit for 2001–2006 BMW 330ci is a complete, height-adjustable system combining monotube gas-pressure dampers with matched springs. Threaded bodies allow roughly 30–50mm of lowering and Triple-C surface coating improves corrosion resistance. Made in Germany and tested under motorsport conditions, the kit provides tunable ride height and performance-oriented damping in a direct-fit package.
