The Bilstein B6 front 36mm monotube strut for the 1999 BMW Z3 M Coupe (left side) upgrades the OE damper while retaining the factory spring. Application-specific valve settings and gas-pressure technology sharpen handling, improve grip and lane stability without requiring new springs. B6 dampers are tested to meet or exceed OE standards and provide vehicle-specific ride tuning for everyday and spirited driving.
