Dynamite Friction 7004-31015 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotor Set

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31015, is a disc brake rotor set built for BMW 3 Series applications from 1991-1999. It is engineered for front and rear use on select BMW 318i, 318is, 325i, 325is, 328i, 328is, 323i, and 323is models.

The drilled and slotted design is made to improve pad bite, clear debris, and reduce heat buildup during braking. The silver GEOSPEC coating and precision machining support OE-style durability, stable braking performance, and a cleaner rotor finish.

• Drilled holes help reduce heat buildup under repeated braking
• Slots clear brake dust and road debris from the rotor surface
• Non-directional finish supports faster, more even pad bed-in
• 100% inspected for balance and critical dimensions
• G3000/G11H18 cast iron construction for OE-spec durability
• Silver-coated rotor surface for corrosion resistance

• Corrosion on exposed rotor surfaces

Installation Notes and Tips

Verify rotor size and axle position before installation on your BMW 318i, 325i, 328i, 323i, or related 3 Series model. For best results, replace rotors in axle pairs and follow proper pad bedding procedures after installation. On 1991 BMW 318i and 318is applications, confirm the vehicle production date is from 11/91.
