The Bilstein B6 rear shock absorber for 1989 Porsche 911 Carrera is a 46mm monotube performance damper intended as an upgrade to OE units while using the factory spring. Tuned for the application, it offers improved handling and safety through vehicle-specific valve settings and gas-pressure technology. Expect better grip, lane stability and ride tuning without necessarily changing springs.
