Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built around axle-specific friction and rotor engineering. For the BMW Z4 rear brake service, the coated rotors provide corrosion protection and a clean installation surface, while the pad compound is formulated for stable friction performance and consistent pedal response. The rotor machining process uses tight tolerances and a non-directional finish to support quieter operation and more even contact during bed-in. Part number 4502-31173 is a practical choice for a rear brake refresh on the BMW Z4.

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

Common Problems This Kit Can Address

• Rear brake noise during stops
• Rust buildup on exposed rotor surfaces
• Uneven braking feel from worn pads and rotors
• Longer stopping distances caused by worn friction material
• Brake pulsation related to rotor wear or finish issues

Installation Notes

Fits 2003-2006 BMW Z4, rear. Confirm rotor size, pad shape, and axle position before installation. The rotors are shipped dry and ready to install, so no oil removal step is required. After installation, follow the vehicle manufacturer’s brake bedding procedure to help the pads and rotors seat properly.

Quality Assurance

Each rotor is machined to OE specifications and inspected for critical dimensions and balance where applicable. DFC states that every rotor in this line is covered by a 12-month warranty against defects in material and workmanship. The 5000 Advanced Brake Pads are post-cured, scorched, and assembled with premium shims to support stable friction and NVH control.
