Dynamic Friction 4804-13028 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction 4804-13028 is a GeoSpec® Coated plain (smooth) disc brake rotor engineered as a direct OE replacement. Part of DFC's trusted GeoSpec line, this rotor is treated with a proprietary silver-gray coating that delivers superior corrosion resistance compared to conventional paint or zinc coatings — and is safely swept away by the friction material during normal break-in.
