Product Details

DFC GEOSPEC rotors are built from G3000/G11H18 cast iron and processed to tight machining tolerances for durability, reliability, and stable braking performance. The coated finish is designed to fight corrosion better than conventional paint or zinc coatings, while the dry-shipped design eliminates the need to clean oil from the rotor before installation. The 5000 Advanced Brake Pads are formulated for consistent friction, with post-curing and scorching steps that reduce initial break-in and support stronger stopping response from the first stop. This rear brake kit is a practical service solution for BMW Z4 owners looking for a complete rotor-and-pad replacement in one box. Part number 4502-31175 is also a useful reference when sourcing rear brake components for the BMW Z4.

Common Reasons for Replacement

• Rear brake noise, vibration, or uneven stopping feel
• Rotor rust, surface corrosion, or worn braking surfaces
• Reduced pad friction or extended stopping distance
• Brake pulsation from rotor wear or thickness variation
• Need for a complete rear brake refresh on a BMW Z4

Installation Notes

Compatible With 2003-2008 BMW Z4 rear brake service. The rotors are shipped dry and ready to install, which can reduce prep time during the brake job. Follow OE service procedures for rotor and pad replacement, inspect related brake components before assembly, and verify rear axle fitment against the vehicle’s brake configuration before installation. Part number 4502-31175 should be matched to the rear application listed for the vehicle.
