Product Details

DFC GEOSPEC coated rotors are machined to tight tolerances and built to OE-style G3000/G11H18 cast iron specifications for durability, reliability, and stability. The silver-gray coating is designed to fight corrosion better than conventional paint or zinc finishes, while the dry-ready surface saves prep time during brake service. The 5000 Advanced ceramic pads are formulated for consistent friction and improved initial bite, and the included hardware is engineered to restore proper spring tension and caliper movement.

Installation Notes

Install on the front axle only. The rotors are processed dry and ready to install without additional cleaning. For best results, inspect caliper condition, pad slides, and brake fluid condition before assembly. Follow the vehicle manufacturer’s torque specifications and perform a proper pad bed-in procedure after installation.

Quality Assurance

Each rotor is 100% inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when needed. DFC states that every rotor meets OE specifications and includes a 12-month warranty against defects in material and workmanship.
