The DFC GeoSpec brake rotor is a fully coated direct replacement disc that ships ready to install with no pre-degreasing needed. Its full GeoSpec coating provides superior corrosion protection over zinc or conventional painted rotors, while the G3000/G11H18 gray iron casting and OE vane design deliver stable braking and proper heat dissipation. Each rotor carries a non-directional finish and is precision cut and mill-balanced for smooth, vibration-free stops.
