Product Details

DFC’s GEOSPEC rotor line is designed around dry, ready-to-install coated rotors that resist rust better than conventional painted or zinc-coated finishes. The rotor casting uses G3000/G11H18 cast iron specifications and is finished to OE-style dimensions for durability, stability, and consistent braking performance. The 5000 Advanced pad formulation is developed for modern vehicle braking demands, with post-curing and scorching steps that help deliver stable friction characteristics and a more consistent first stop. For Mazda 3 and Mazda 3 Sport rear brake service, part number 4512-80110 provides a matched rotor-and-pad package for 2017-2018 Mexico-built vehicles excluding Electric Parking Brake models.
