The Bilstein B16 (PSS9) suspension kit for 2004 Mazda RX-8 is a direct-fit front and rear system that combines monotube dampers with springs tuned to the RX-8 for improved handling and adjustable ride height. The nine-stage manual damper adjusts rebound and compression to suit different driving conditions. Threaded, zinc-coated bodies permit about 30–50mm lowering; Triple-C corrosion protection, German manufacture, and Nürburgring‑proven development deliver durable, tunable control.
