Installation Notes and Tips

Verify the rear left position, bolt pattern, center hole diameter, and rotor dimensions before installation. Because this rotor uses a directional brake surface, install it in the correct orientation for the rear left side. Inspect pads, caliper condition, and hub surface during replacement to help ensure even contact and proper rotor seating. Confirm fitment by model year before ordering, especially on 2019-2026 Acura RDX and 2017-2021 Honda Clarity applications.
