• G3000/G11H18 cast iron rotor specification engineered to OE dimensions and stability targets
• Non-directional rotor finish to support quicker pad bed-in and smoother braking
• 100% inspected rotors, including balance checks on vented rotors

Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are built as a complete front brake solution for BMW owners who want matched components from the same kit. The rotors are machined to tight tolerances, finished for even pad contact, and inspected to meet OE specifications. The pads are formulated for consistent friction across a range of driving conditions, making this kit a practical choice for BMW Z3, BMW Z4, and select BMW 3 Series front brake repairs.

This part number, 4502-31135, is a straightforward option when replacing worn front rotors and pads on vehicles such as the BMW 328i, BMW 325i, and BMW 320i. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Kit Helps Address

• Brake pulsation caused by worn or uneven rotors
• Squealing or noise from aged pad material
• Reduced stopping performance from thin or heat-affected components
• Rust buildup on exposed rotor surfaces
• Longer service time from separate rotor and pad sourcing
