Product Line Details

DFC Brake Rotors - GEOSPEC Coated is Dynamite Friction’s coated rotor line for drivers who want a front rotor replacement with added surface protection. The GEOSPEC coating is applied to help resist rust on exposed areas while maintaining the braking surface needed for normal rotor operation.
