Dynamic Friction 4004-76083 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4004-76083 GeoSpec Coated Plain Brake Rotor is a premium OE-replacement disc brake rotor engineered for long-lasting performance and superior corrosion resistance. Featuring DFC's patented GeoSpec® coating, this rotor forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings—keeping your brakes protected before and after installation.

Each rotor is cast from premium G3000/G11H18 iron and CNC-machined to the tightest tolerances available, then finished with a non-directional surface treatment to promote a faster, more even brake pad bed-in and quieter, smoother stops. All vented rotors are 100% electronically mill-balanced to eliminate vibration at any speed, and every unit passes a full OE specification inspection before leaving the facility.
