Product Details

DFC brake kits are built to simplify brake service by combining matched components in one package. The GEOSPEC coated rotors use G3000/G11H18 cast iron and are machined to OE-level tolerances, then inspected for balance and critical dimensions. The 5000 Advanced ceramic pads are formulated for consistent friction and improved initial bite, while the included hardware is engineered to restore proper caliper movement and spring tension on the rear axle.
