DFC GEOSPEC Brake Kit for BMW 3 Series and 4 Series

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4504-31063, combine coated brake rotors and matched friction material in one service kit. It is built for BMW applications with standard brakes across multiple 3 Series and 4 Series models from 2013-2020.

Key Features

• Complete disc brake kit with rotors and pads for front and rear service
• GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry, ready-to-install rotor surface with no oil cleaning required
• G3000/G11H18 cast iron rotor construction for OE-style durability and stability
• Non-directional rotor finish for even pad bed-in and smoother braking
• 5000 Advanced Brake Pads are post-cured and scorched to reduce initial break-in time
• Premium rubber-steel-rubber shims help improve noise, vibration, and harshness control

Product Details

The DFC 5000 Advanced Brake Pads in this kit are processed for stable friction performance and consistent stopping response. The pads are post-cured, then scorched to remove uncured bonding agents, which helps reduce the initial bedding period. DFC also uses premium rubber-steel-rubber shims to support quieter operation and improved pedal refinement.

The GEOSPEC rotors are coated to resist rust better than conventional painted or zinc-coated rotors. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance. This makes part number 4504-31063 a practical choice for BMW 430i, BMW 330i xDrive, BMW 328i xDrive, and other listed applications that need a complete brake service solution.

Used For

• Replacing worn rotors and pads on BMW 3 Series and 4 Series vehicles
• Addressing brake pulsation caused by rotor wear or uneven surfaces
• Restoring braking response after pad material has reached service limits
• Reducing brake noise associated with worn pads or degraded shims
• Improving corrosion resistance on exposed rotor surfaces
