Product Details

DFC’s GEOSPEC rotor line is engineered to match OEM specifications for fit, durability, and braking consistency. Each rotor is machined to tight tolerances, finished for even pad contact, and inspected for critical dimensions and balance. The 5000 Advanced ceramic pads are formulated for stable friction performance and cleaner operation, while the included hardware is designed to restore proper spring tension and caliper movement during brake service.
