Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads is engineered as a complete rear brake service solution for BMW X3, BMW X4, and BMW 530i models listed below. The rotors use a G3000/G11H18 cast iron specification and a silver-gray protective coating that resists corrosion better than conventional paint or zinc finishes. Each rotor is machined to tight tolerances, finished non-directionally, and inspected for critical dimensions and balance before release. The pads are formulated for stable friction performance and are assembled with premium shims to support quieter operation.

Installation Notes

Confirm rear-axle brake configuration before ordering, since this kit is listed for standard brakes with either optional design full cast rotors or original design aluminum hat rotors. The rotors are shipped dry and ready for installation, which helps reduce prep time during service. Follow the vehicle manufacturer’s brake service procedures, clean all mating surfaces, and bed the pads in according to standard brake break-in practice.

Quality Assurance

DFC states that each rotor is inspected for critical attributes and balance, with vented rotors corrected as needed during the mill-balance process. The rotors are covered by a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched to support consistent friction performance.
