The Bilstein B12 (Pro-Kit) suspension kit for 2010–2013 Mazda3 combines Bilstein performance dampers with Eibach Pro-Kit springs tuned for the application. The complete kit offers moderate fixed-height lowering—typically between 24–40mm depending on fitment—and matched damping and spring rates to deliver more precise response and improved driving dynamics while providing a balanced lowered stance suited to the vehicle.
