Dynamic Friction 4804-76047 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-76047 is a GeoSpec Coated plain disc brake rotor engineered to deliver OEM-quality braking performance with superior corrosion resistance. Featuring DFC's proprietary GeoSpec® coating, this rotor develops a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings — and it ships dry, ready to install with no pre-degreasing required.

Each rotor is cast from premium G3000/G11H18 iron and CNC-machined to the tightest tolerances in the market, ensuring a precise, rattle-free fit. The smooth, plain rotor face features a non-directional finish that promotes a faster, more even brake pad bed-in for quieter, smoother stops right out of the box. All vented rotors undergo 100% electronic mill-balance inspection and correction, eliminating vibration at any speed.
