Installation Notes and Tips

Verify rear left position, bolt pattern, center bore, and rotor dimensions before installation. Confirm that the vehicle uses the listed 278 mm outside diameter, 114.3 mm bolt circle diameter, and 70.7 mm center hole diameter. Because this rotor is directional, install it in the correct orientation for the rear left side. Always inspect pads, caliper condition, and hub mounting surfaces during brake service.
