Product Line Details

The DFC GEOSPEC rotor line focuses on corrosion resistance and installation efficiency. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging avoids the need to clean oil from the rotor before service. The 5000 Advanced Brake Pads are formulated for stable friction performance and use shims to help reduce noise, vibration, and harshness.
