• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed rotors arrive ready to install
• Non-directional rotor finish supports even pad bed-in and smoother braking
• 5000 Advanced pads are post-cured and scorched for stable friction performance
• Rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Hardware uses PTFE coating, vulcanized rubber, and stainless steel construction

Product Details

DFC’s GEOSPEC rotor line is engineered to OE-style cast iron specifications and machined to tight tolerances for durability and consistent braking. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry-ready design eliminates the need to clean oily rotors before installation. The 5000 Advanced ceramic pads are formulated for stable friction and reduced break-in time, making this kit a practical choice for BMW rear brake service. Part number 4512-31068 is listed for rear standard-brake applications on the BMW X3, BMW X4, and BMW 530i family.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Uneven braking caused by rotor wear or corrosion
• Longer stopping distances from depleted friction material
• Brake pulsation related to rotor condition
• Reduced pedal confidence during routine BMW rear brake service
