Dynamic Friction 4812-27172 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4812-27172 is a GeoSpec fully coated plain brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec coating, this rotor forms a durable, attractive silver-gray finish that provides superior corrosion protection compared to conventional paint or zinc coatings.

Each rotor is processed dry and ships ready to install — no pre-cleaning or degreasing required. The GeoSpec coating is designed not to contaminate friction or rotor surfaces, ensuring a proper brake pad bed-in from the very first stop.
