Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built for drivers who want a complete front brake service package with matched components. The rotors are cast to OEM-style G3000/G11H18 specifications, machined to tight tolerances, and inspected for balance and critical dimensions. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry-ready design eliminates the need to clean oil from the rotor before installation. The 5000 Advanced pads are formulated for stable friction and are assembled with premium shims to support quieter operation. This kit is a direct fit for BMW Z4 front brake service on 2011-2016 models, including applications with optional design full cast front rotors and front rotors with original design aluminum hat. Part number 4502-31223 is also useful when cross-checking service records or ordering by catalog reference.

Common Brake Issues This Kit Can Address

• Front brake rotor wear, scoring, or thickness variation
• Brake pad wear or reduced stopping performance
• Brake noise during light or moderate stops
• Rust buildup on exposed rotor surfaces
• Uneven brake feel during pad break-in
