Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and vehicle-specific brake package before installation. This rotor is listed for front left positions only, and several BMW applications note standard brakes, optional full cast rotors, original aluminum hat rotors, or M Sport brakes. Confirm the exact brake configuration on the vehicle before ordering. For 2019 BMW X5 applications, the fitment notes also reference a disc brake pad wear sensor.
