Common Problems This Rotor Can Address

• Rear brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or below-spec rotor thickness
• Noise or uneven braking from deteriorated rotor surfaces
• Loss of braking consistency from heat-worn rear rotors
• Replacement needs for BMW X5 and BMW X6 rear brake service

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake package before installation. This rotor uses a vented design, 5 lug holes, and a 120 mm bolt circle, so confirm the vehicle’s rear brake setup matches the listed specifications. For 2016-2018 BMW X5 and 2016-2018 BMW X6 applications, confirm the vehicle is not equipped with M Sport Brakes.
