Dynamic Friction 4002-31089 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-31089 GeoSpec Coated Brake Rotor is an OE-replacement plain disc brake rotor engineered to deliver reliable, quiet, and long-lasting braking performance. Featuring DFC's proprietary GeoSpec® corrosion-protection coating, this rotor arrives ready to install straight out of the box — no degreasing or additional preparation required.
