Product Details

DFC built this brake kit for drivers who want a direct rear brake service package with OE-style fit and finish. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required to support stable braking performance. The ceramic pad formulation is developed for consistent friction across a wide range of vehicle applications, including BMW 330i, BMW M340i, BMW Z4, and Toyota GR Supra rear brake service.

Part number 4512-31265 is a practical choice for rear brake replacement on 2019-2022 BMW 330i, 2020-2021 BMW M340i, and 2020-2021 Toyota GR Supra applications that call for DFC GEOSPEC coated rotors with 5000 Advanced Brake Pads. This kit is also listed for additional rear-fit BMW and Toyota models with original-design aluminum hat rotors or optional full cast rotor configurations.

Common Brake Issues This Kit Addresses

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by fatigued or corroded hardware
• Reduced stopping consistency from aged pad friction material
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from worn caliper hardware

Installation Notes

Rear brake service on these applications should follow the vehicle’s rotor design and brake package notes exactly, especially on BMW M Sport and Motorsport Engineering Package vehicles. Verify whether the vehicle uses original-design aluminum hat rotors or optional full cast rotors before ordering. Clean hub surfaces thoroughly, inspect caliper slides, and follow proper pad bed-in procedures after installation.

Quality Assurance

Each DFC GEOSPEC rotor is inspected to OE specifications after machining, and vented rotors are checked for balance. The rotors carry a 12-month warranty against defects in material and workmanship.
