Dynamite Friction 4504-31008 Disc Brake Kit - Front and Rear

Brake Kit for BMW 320i, 323Ci, 323i, 328i

Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4504-31008, is a front and rear disc brake kit for select BMW 3 Series applications. It combines coated rotors with advanced friction pads to support consistent braking performance, cleaner installation, and OE-style fitment for the listed vehicles.

Key Features

• Complete disc brake kit with rotors and pads for front and rear service
• DFC 5000 Advanced Brake Pads are post-cured for stable friction performance
• Pads are scorched to reduce initial break-in time and improve first-stop response
• Premium rubber-steel-rubber shims are used to improve noise, vibration, and harshness control
• GeoSpec coated rotors feature a silver-gray corrosion-resistant finish
• Rotors are shipped dry and ready to install, with no oil coating to clean off
• Machined to tight tolerances with a non-directional finish for smoother pad bed-in
• Vented rotors are balance-inspected and corrected when needed

Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built around matched friction and rotor specifications for service work on BMW 320i, 323Ci, 323i, and 328i models. The brake pads are formulated for stable friction output, while the coated rotors use G3000/G11H18 cast iron and precision machining to meet OE-style dimensional requirements. This part number, 4504-31008, is a practical choice when replacing worn brake components on 1996-2005 BMW 3 Series vehicles listed below.

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

What It Helps Address

• Brake pulsation from worn or uneven rotors
• Reduced stopping performance from aged pads
• Brake noise caused by worn friction material or poor pad fit
• Rust buildup on exposed rotor surfaces
• Longer service time caused by oil-coated replacement rotors

Installation Notes and Fitment

• Fits 2001-2005 BMW 320i, front and rear
• Fits 2000 BMW 323Ci, front and rear
• Fits 1998-2000 BMW 323i, front and rear
• Fits 1996-1999 BMW 328i, front and rear

Before installation, confirm rotor size, pad shape, and brake system configuration against the vehicle. The rotors arrive dry and ready for installation, and the pad surface is prepared to reduce the need for extended break-in. For best results, inspect calipers, slides, and brake fluid condition during service.

Quality Assurance

DFC GeoSpec rotors are 100% inspected for critical dimensions and balance, and every rotor is checked to meet OE specifications. The rotors carry a 12-month warranty against defects in material and workmanship.
