Bilstein B8 Performance Plus (Sport) front strut insert for 1989-7/1990 E34 525i/535i/M5. It may fit other E34 models that have been changed/updated to the earliest front mount. This application uses a dome-shaped dust cap with
2.5" underside diameter and an
M12 shock stem. It may have a 19mm hex nut.
Bilstein B8 Performance Plus shocks (formerly known as Sport shocks) are designed specifically for lowered springs and high-performance driving. While HD shocks are engineered to work with the stock springs, Sport shocks are to be used with shorter springs, such as from Eibach or H&R. The B8 shocks are what Bilstein uses with their B12 shock & spring packages. B8 Sport shocks are shorter to better match the new ride of height of the lowered springs and inverted (upside down) to reduce unsprung weight at the hub. The shocks are valved to be stiffer than original to better control spring and body motions. Bilstein uses Digressive Valving to give a firm and controlled ride on slow shock movements but be softer and more compliant on bumps and rough pavement (fast shock speeds).
