Installation Notes and Tips

Rear brake service should be performed with the correct vehicle-specific fitment confirmed before installation. The rotors are shipped dry and ready to install, which helps reduce prep time during a standard brake job. For best results, follow proper bedding procedures after installation so the pads and rotors can seat evenly.

Quality Assurance

Each rotor is manufactured to OE specifications and passes 100% inspection for critical attributes. Vented rotors are balanced and corrected as needed during production. The rotors include a 12-month warranty against defects in material and workmanship.
