P/N: sto128.34140L

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 340mm rotors for Non-MSport Calipers. MSport calipers are easily identifiable as they are blue in color and require a 370mm brake rotor/disk.
