Installation Notes

Confirm rear axle fitment by year, model, and any listed configuration notes before ordering. The rotors are processed dry and do not require oil removal before installation. A proper brake service should include inspection of calipers, slides, and related wear items before the new kit is installed.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance where applicable. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-73157 is built to OE-style specifications for rear brake service on select Audi models.
