Bilstein B12 Pro-Kit – BMW 335i / 335d (E90 RWD)

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.

Dampers and springs are tuned together for each specific vehicle rather than sold as generic parts, which is what BILSTEIN calls its Professional Cornering System (PCS): precise response, excellent performance and predictable control, plus a lower, action-ready stance.

The B12 (Pro-Kit) is the product of two companies at the top of their industries: the shock absorber experts at BILSTEIN and the spring professionals at EIBACH.
