Product Details

The DFC GEOSPEC rotor coating is formulated to resist rust better than conventional paint or zinc finishes, while also eliminating the need to clean oil from the rotor before installation. The rotors are machined to tight tolerances, balanced where required, and inspected for critical dimensions to support OE-level fit and function. The 5000 Advanced brake pads are prepared to deliver consistent friction from the first stop and are assembled with shims that support quieter operation. This part number 4502-31151 is a practical choice for BMW rear brake service when you want matched rotors and pads from the same kit.

Installation Notes

Rear brake service on these BMW applications is typically completed as an axle set. The coated rotor surface is ready to install without additional prep, and the coating is removed naturally by the brake pads during normal use. Verify rear fitment by model year before ordering, and confirm rotor and pad condition on the opposite side of the axle during service. Part number 4502-31151 is listed for rear applications only.

Quality Assurance

DFC GEOSPEC rotors are backed by a 12-month warranty against defects in material and workmanship. Each rotor is inspected to meet OE specifications, and the brake pads are post-cured for stable friction performance. This kit is built to support dependable rear brake replacement for BMW 320i, 323Ci, 323i, and 328i models.
