Dynamite Friction 4502-31058 Disc Brake Kit - Front

Brake Kit for BMW Front Applications

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is built for front brake service on select BMW models. It combines coated rotors and advanced friction pads in one package for drivers replacing worn front brake components on 2009-2017 BMW 750i, 750Li, 750i xDrive, 750Li xDrive, 550i GT, and 550i GT xDrive applications.

Part number 4502-31058 is a front disc brake kit for BMW 750i and BMW 550i GT fitments that require OE-style rotor and pad replacement. The DFC GEOSPEC rotor finish helps resist corrosion, while the 5000 Advanced pads are formulated for stable friction and quieter operation.

• Dry-processed rotors ready for installation without oil removal
• Non-directional rotor finish for even pad bed-in and smoother braking
• 5000 Advanced pads are post-cured and scorched for consistent friction
• Rubber-steel-rubber shims help reduce noise, vibration, and harshness
• OE-spec cast iron rotor construction and tight machining tolerances
• Part number 4502-31058

Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a service kit for front brake replacement on BMW luxury sedans and GT models. The rotors are machined to OE specifications, inspected for critical dimensions, and finished with a non-directional surface to support even pad contact. The pads are built for stable friction performance and reduced break-in time, making this kit a practical choice for front brake refresh work on BMW 750i, 750Li, 750i xDrive, 750Li xDrive, 550i GT, and 550i GT xDrive vehicles.

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

What It Helps Address

• Front brake noise during stopping
• Rotor rust and surface corrosion
• Brake pulsation from worn front rotors
• Reduced stopping performance from worn pads
• Uneven pad bedding after brake service

Installation Notes

Fits 2010-2017 BMW 550i GT xDrive, front. Fits 2010-2015 BMW 550i GT, front. Fits 2009-2015 BMW 750i, front. Fits 2010-2015 BMW 750i xDrive, front. Fits 2009-2015 BMW 750Li, front. Fits 2010-2015 BMW 750Li xDrive, front.

For BMW applications with original design aluminum hat rotors or optional full cast front rotors, verify the rotor style before installation. The rotors are shipped dry and ready to install, which helps reduce prep time during brake service. Follow standard brake bedding procedures after installation for consistent pad transfer.

Quality Assurance

DFC states that each rotor is inspected for balance and critical dimensions, with vented rotors electronically mill-balanced when needed. The rotors are covered by a 12-month warranty against defects in material and workmanship. Part number 4502-31058 is built to OE-spec expectations for front brake service.
