Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered for front brake service on a wide range of BMW 2 Series, 3 Series, 4 Series, and M Performance models. The coated rotor surface helps resist rust better than conventional paint or zinc finishes, while the dry-ready design eliminates the need to clean oil-coated rotors before installation. The pads are formulated for stable friction performance and quieter operation, making this kit a practical choice for BMW 230i, 330i, 430i, M240i, M235i, 328i, and related front brake applications. Part number 4502-31231 is built to match OE specifications for durability, reliability, and stability.

Quality Assurance

Each DFC GEOSPEC rotor is machined to tight tolerances, inspected for critical dimensions, and, on vented rotors, balance-checked and corrected when needed. The kit includes a 12-month warranty against defects in material and workmanship. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
