Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify rotor thickness with a micrometer to confirm it meets or exceeds the nominal thickness of 1.57 inches (40 mm). Since this rotor is non-directional, it can be installed on either side of the vehicle. Use proper torque specifications for the eight mounting bolts to secure the rotor firmly. Because this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system if applicable.
