Dynamic Friction 4824-31188 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4824-31188 is a GeoSpec Coated Plain (Smooth) Disc Brake Rotor engineered as a direct OE replacement. DFC's GeoSpec coating program applies a fully coated, patented silver-gray finish inside and out, providing superior rust and corrosion resistance compared to conventional paint or zinc coatings — keeping your brake system protected before and long after installation.

Each rotor is cast from premium G3000/G11H18 iron and CNC-machined at DFC's state-of-the-art facilities to the tightest tolerances in the market. A non-directional surface finish promotes a faster, more even brake pad bed-in process, resulting in quieter and smoother stops from day one. All vented rotors undergo 100% electronic mill-balancing and pass a full inspection station verifying all critical attributes for OE compliance.
