The DFC Quickstop drilled brake rotor is a direct OE replacement for the left rear of the BMW M2, M3, and M4. It is cast from premium G3000/G11H18 grade iron and cross-drilled to shed heat and brake gases, then precision mill-balanced for smooth, vibration-free stops. The 370mm disc keeps the OE vane configuration for proper heat dissipation and ships with a non-directional finish that speeds pad break-in.
