The Bilstein B6 front left strut assembly for the 2012 BMW Z4 sDrive35i is a 36mm monotube damper offered as a performance-oriented upgrade to the original equipment unit while retaining the factory spring. B6 dampers use application-specific valve tuning and gas-pressure technology to improve grip, lane stability and handling. Each unit is tested to meet or exceed OE standards, delivering enhanced safety and Bilstein quality without requiring new springs.
