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.
