The Bilstein B12 (Pro-Kit) suspension kit for 2015–2020 BMW M4 Coupe combines Bilstein performance dampers with Eibach Pro-Kit springs matched to the application. This complete kit delivers moderate fixed-height lowering—generally between 24–40mm depending on fitment—and tuned damper-and-spring pairing for improved response and driving dynamics. The kit balances suspension performance with a lowered stance for a refined, application-specific setup.
