Dynamite Friction 4502-31061 Disc Brake Kit - Front

Front Brake Kit for BMW E30 Applications

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit, part number 4502-31061, combines coated front rotors and matched friction material for select BMW 3 Series applications. It is built for drivers servicing front brakes on 1984-1991 BMW 325e, 325es, 325i, 325is, 325iX, 318i, and 318is models with the listed caliper configurations.

Key Features

• Complete front disc brake kit with rotors and pads
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed rotors arrive ready to install
• G3000/G11H18 cast iron rotor construction for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 100% inspected rotors with balance correction on vented units
• DFC 5000 Advanced pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness

Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a front brake service solution for BMW 318i, 318is, 325e, 325es, 325i, 325is, and 325iX applications. The rotors are machined to tight tolerances, finished non-directionally, and inspected to meet OE specifications, while the pads are formulated for consistent friction and improved pedal feel from the first stop. This part number, 4502-31061, is a practical choice for front brake refresh work on BMW E30 platforms where corrosion protection, fit accuracy, and quiet operation matter.

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

What This Brake Kit Helps Address

• Front brake pulsation from worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Noise and vibration during braking
• Reduced stopping performance from worn pads
• Longer service time caused by rotors that require extra prep before installation

Verify caliper type and production date before ordering, especially on 1991 BMW 318i and 318is models. The dry-coated rotors are ready for installation without additional cleaning, and the coating is removed naturally by the brake pads during normal use.

Quality Assurance

Each rotor is manufactured to OE-style specifications, inspected for critical dimensions, and covered by a 12-month warranty against defects in material and workmanship. The pad set is post-cured, scorched, and assembled with premium shims to support stable braking performance and quieter operation.
