Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify that the bolt hole pattern matches the vehicle’s hub (5-lug, 1/2-20 bolt hole diameter, 127 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 30.86 mm. Clean the rotor surface of any protective coatings or oils before mounting to ensure optimal pad contact.
