Installation Notes

Verify rotor design before ordering, since the BMW X3 and BMW X4 applications listed here use different rotor configurations. Inspect calipers, pad hardware condition, and hub surfaces during brake service, and follow the vehicle manufacturer’s torque and bedding procedures after installation. Part number 8504-31085 should be matched to the exact year, model, and rotor design shown in the fitment data.
