Installation Notes

Install on the rear axle only where the vehicle configuration matches the listed rotor design and brake package. The rotors are shipped dry and ready to install, which helps reduce prep time during brake service. Verify rotor style, brake package, and any wear sensor requirements before installation on BMW 740i, X5, X6, or X7 rear brake systems.

Quality Assurance

Each rotor is machined to tight tolerances, checked for balance on vented designs, and inspected against OE specifications after processing. DFC backs the rotors with a 12-month warranty against defects in material and workmanship. Part number 4502-31280 is built as a complete rear brake kit for consistent service results.
