Product Information
R1 Concepts 631-31054D is a single drilled and slotted replacement rotor for the front left corner of the 2001-2006 BMW M3 (E46). It is cast from G3000 grade iron with silver zinc plating over the whole rotor for corrosion protection, and it replaces the factory front rotor with the original caliper and hardware. The drilled and slotted face is side specific, so the front right rotor is a separate part number (631-31055D).
