Installation Notes and Tips

Confirm rear axle fitment before ordering, since this kit is for rear applications only. Inspect calipers, slides, and mounting points during service, and replace any damaged components before installation. The rotors are shipped dry and ready to install, so no oil removal step is required. Follow the vehicle manufacturer’s brake service procedure and torque specifications for proper results.

Quality Assurance

DFC states that each rotor is inspected for critical dimensions and balance, and the finished rotor is checked against OE specifications. The rotors include a 12-month warranty against defects in material and workmanship.
