This Dynamic Friction Company GeoSpec coated brake rotor is a cross-drilled, direct-fit performance rotor for the rear left corner. It is cast from premium G3000/G11H18 iron with an OE vane configuration, then cross-drilled with chamfered holes to shed heat and clear water and gas from the pad face. DFC's full-coverage GeoSpec coating protects the entire rotor with a durable silver-gray anti-corrosion finish that arrives clean and ready to install with no degreasing. Each rotor is CNC machined and 100 percent mill balanced for smooth, vibration-free stops.
