The stock brakes on your BMW are okay for street duty but often fall short during spirited driving. We are now offering a brake upgrade kit for the performance street-oriented driver. For street applications, Stoptech cross-drilled rotors are a great performance upgrade.

These are 380mm rotors for MPerformance Calipers. MPerformance calipers are easily identifiable as they are 4-piston and require a 380mm brake rotor/disk.

Centric premium rotors utilize an Electrocoating finish that provides long-lasting corrosion protection. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. Phosphate finishes utilized by other manufacturers provide only minimal protection from the elements; these finishes are generally only effective for the shipping and storage portion of a rotor's life. The addition of heat and moisture eliminates the effectiveness of phosphate finishes resulting in immediate corrosion once installed in the vehicle.
