Bilstein B12 (Pro‑Kit) suspension kit pairs Bilstein B8 Performance dampers with Eibach Pro‑Kit springs tuned for each application to provide a fixed lowering solution and improved dynamics. The kit offers moderate lowering—typically between about 24–40mm depending on application—delivering predictable control, precise response and enhanced driving dynamics while preserving safety reserves. This set is specific to 2013–2015 BMW ActiveHybrid 3 front and rear fitment.
