The Story
Brake Kit for BMW M550i xDrive
The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware is a complete disc brake kit for select BMW M550i xDrive applications. It combines coated rotors, ceramic brake pads, and matching brake hardware to support consistent braking performance, reduced noise, and easier service work.
Key Features
- Part number 4514-31109
- Fits 2018-2020 BMW M550i xDrive, front and rear
- DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
- 5000 Advanced ceramic brake pads with post-cured friction material
- Scorched pads for reduced initial break-in time
- Premium rubber-steel-rubber shims for improved NVH control
- Non-directional rotor finish for more even pad bed-in and smoother stops
- Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel
Product Details
DFC designed this brake service kit for drivers who need OE-style braking components in one package. The GEOSPEC rotors are machined to tight tolerances, processed dry, and ready to install without oil removal or extra prep. The 5000 Advanced ceramic pads are built for stable friction performance and quieter operation, while the included hardware is engineered to restore proper caliper movement and spring tension. This part number, 4514-31109, is a direct service solution for BMW M550i xDrive front and rear brake replacement.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Brake Issues This Kit Addresses
- Brake noise from worn pads or fatigued hardware
- Uneven pad wear caused by corroded or weakened hardware
- Longer stopping distances from worn rotors and pads
- Brake vibration or pulsation from rotor wear
- Reduced braking consistency during everyday driving
Installation Notes
Fits 2018-2020 BMW M550i xDrive, front and rear. One fitment row notes compatibility with aluminum hat rotors designed to original specifications and includes a disc brake pad wear sensor; another notes an optional design for full cast disc brake rotors. Verify rotor style and sensor requirements before installation. The rotors are shipped dry and ready to install, which helps reduce prep time during brake service.
Quality Assurance
DFC states that each rotor is inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when needed. The rotors are backed by a 12-month warranty against defects in material and workmanship.
