Product Line Details

DFC GEOSPEC rotors are coated to resist rust and arrive dry, so they do not require cleaning before installation. The rotor design uses G3000/G11H18 cast iron and is machined to OE-style tolerances, with balance inspection on vented rotors and a final inspection of critical dimensions. The 5000 Advanced pad compound is post cured and scorched to reduce initial break-in time and deliver stable friction from the first stop. Part number 4512-31278 is built around these matched components for front axle service.
