The DFC GeoSpec Coated brake rotor is a blank, non-directional rear disc that replaces the factory rotor on the BMW M3 and M5. It is fully coated for superior corrosion protection over zinc or conventional paint, cast from premium G3000/G11H18 iron, and 100% precision mill-balanced for smooth, vibration-free stops. Each rotor arrives ready to install with no pre-degreasing required.
