Dynamite Friction 7004-31042 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotors for BMW

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver are performance disc brake rotors built for BMW 525i and BMW 528i applications. Part number 7004-31042 combines drilled and slotted rotor design with GEOSPEC coating and OE-style machining for consistent braking response and clean fitment.

Key Features

• Drilled holes help reduce heat buildup during repeated braking
• Slots clear brake dust and road debris from the pad surface
• Silver GEOSPEC coating supports corrosion resistance on exposed surfaces
• G3000/G11H18 cast iron construction follows OEM-style durability targets
• Non-directional finish promotes even pad bed-in and quieter stops
• 100% inspected for balance and critical dimensions after machining

Product Details

The DFC Rotors-Drilled and Slotted-Silver line is built for drivers who want a rotor upgrade with OE-focused manufacturing standards. These rotors are machined to tight tolerances, finished for smoother pad transfer, and checked for balance before release. Part number 7004-31042 is a direct fit for 1996-2000 BMW 528i, front and rear, and 2001-2003 BMW 525i, front and rear.

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

Common Brake Issues Addressed

• Excess rotor heat during stop-and-go or repeated braking
• Brake pad glazing from debris buildup on the rotor face
• Uneven braking feel caused by inconsistent pad contact
• Noise and vibration from rotors that are out of balance or unevenly finished
• Corrosion on exposed rotor surfaces

Installation Notes

Install 7004-31042 on the correct axle position for your BMW 525i or BMW 528i application. Clean the hub mounting surface before installation, verify rotor runout, and follow the vehicle manufacturer’s brake service procedure. Proper pad bedding is important for consistent performance after installation.

Quality Assurance

DFC states these rotors are inspected at multiple stages, including balance correction where needed and final dimensional verification against OE specifications. Part number 7004-31042 includes a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
