Dynamite Friction 4512-31083 Disc Brake Kit - Front

Front Brake Kit for BMW 740i, 840i, 540i and X7

DFC Friction part 4512-31083 is a front disc brake kit built for select BMW applications with standard brakes and specified rotor designs. It combines GEOSPEC coated rotors, 5000 Advanced ceramic brake pads, and matching hardware for a complete front brake service on covered 2016-2023 BMW models.

Key Features

• GEOSPEC coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
• Dry-processed rotors arrive ready to install, with no oil coating to clean off
• G3000/G11H18 cast iron rotor construction matched to OE specifications
• Non-directional rotor finish for more even pad bed-in and quieter stopping
• 5000 Advanced ceramic pads are post-cured and scorched for stable friction and reduced break-in time
• Premium rubber-steel-rubber shims help improve noise, vibration, and harshness control
• Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel for corrosion resistance

What This Brake Kit Helps Address

• Front brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor surfaces
• Uneven pad transfer or inconsistent braking feel
• Premature or uneven pad wear from aged hardware
• Longer installation time caused by oil-coated replacement rotors

Installation Notes

Compatible With front brake service on the listed BMW applications, including standard brakes and the rotor configurations noted in fitment. The dry rotor coating is swept away by the pad during normal braking, so no special preparation is required before installation. For best results, inspect calipers, slides, and wear sensors during service and follow the vehicle manufacturer’s brake bedding procedure after installation.

Quality Assurance

Each rotor is machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. DFC states that the rotors are built to OE specifications and the kit includes a 12-month warranty against defects in material and workmanship. Part number 4512-31083 is engineered for consistent front brake service on covered BMW 740i, 840i, 540i, and X7 applications.
