Product Details

DFC GEOSPEC coated rotors are machined to tight tolerances and built to OE specifications using G3000/G11H18 cast iron. The coating is designed to resist rust better than conventional paint or zinc finishes, while the dry shipping process saves time during brake service. The rotors are finished for balanced operation and consistent contact with the pad surface.

The 5000 Advanced brake pads are formulated for modern braking demands and are assembled with premium shims to improve pedal feel and reduce brake noise. The included hardware is engineered to restore proper spring tension and caliper movement, which is important on higher-mileage rear brake repairs. This DFC brake kit is a practical choice for BMW 323i rear brake replacement, BMW 328is rear brake service, and other listed BMW 3 Series rear applications.

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

Common Problems This Kit Can Address

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from worn hardware
• Reduced braking smoothness during stop-and-go driving
• Brake pulsation caused by rotor wear or finish issues

Installation Notes
