Dynamic Friction 4504-31112 GeoSpec Coated Plain Disc Brake Rotor Kit

The Dynamic Friction Company 4504-31112 is a GeoSpec Coated Plain Disc Brake Rotor kit engineered as a direct OEM replacement for passenger cars, SUVs, and light trucks. DFC's GeoSpec coating forms a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings, providing superior corrosion protection both before and after installation.

Each rotor is processed dry, shipped dry, and ready to install right out of the box — no degreasing or additional prep work required. The patented GeoSpec coating is safely swept away by the friction material during bed-in, with no harmful effects on braking performance.

Key Features:
