The DFC 604 Series GeoSpec is a fully coated front brake rotor cast from premium G3000/G11H18 grade iron and finished with a GeoSpec corrosion-protection coating across the entire rotor, including the braking surface. It installs ready to run with no pre-degreasing step and provides superior corrosion resistance over zinc or conventional paint. Each rotor is precision cut and 100% mill-balanced for smooth, vibration-free braking.
