Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.803 inches (20.400 mm) before installation. Clean the hub surface and mounting area to prevent uneven rotor seating. Use proper torque specifications for the five lug bolts with a 4.252 inch (108.000 mm) bolt circle diameter. This rotor does not include bearings or ABS tone ring, so verify compatibility with your vehicle’s braking system. Proper bedding-in of brake pads after installation is recommended for optimal performance.
