Dynamic Friction 4812-42116 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4812-42116 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 forms a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings — and is shipped dry, ready to install right out of the box with no pre-degreasing required.

Constructed from premium G3000/G11H18 cast iron, each rotor is CNC-machined to the tightest tolerances available, then finished with a non-directional surface treatment to promote a faster, more even brake pad bed-in for quieter, smoother stops from the first drive. All vented rotors undergo 100% electronic mill-balancing to eliminate vibration at any speed.
