Bilstein B12 Pro Kit – BMW 335i (E92 Coupe)

OVERVIEW

The BILSTEIN B12 (Pro-Kit) is a matched, fixed-height performance suspension package: a complete set of BILSTEIN monotube dampers paired with application-specific EIBACH Pro-Kit progressive-rate lowering springs, providing moderate lowering between 24 and 40 mm depending on application.

The B12 (Pro-Kit) is the result of two companies atop their industries collaborating to present a complete suspension solution for the passenger car market: the shock absorber experts at BILSTEIN and the spring professionals at EIBACH. The system consists of four high-performance BILSTEIN dampers and four EIBACH lowering springs, matched for the best combination of handling and comfort.
