Dynamite Friction 7004-31039 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotor Set

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31039, is a performance brake rotor set built for BMW applications that need stronger pad bite and consistent braking response. It is engineered for front and rear use on select 2013-2020 BMW 3 Series and 4 Series models.

The drilled and slotted design helps evacuate heat, clear brake dust and road debris, and reduce pad glazing. The silver GEOSPEC coating and OE-style cast iron construction support durability, stability, and a cleaner finish for daily driving or spirited street use.

• Drilled holes help reduce heat buildup during repeated stops
• Slots clear debris and help maintain pad contact
• Non-directional finish supports faster, more even pad bed-in
• Machined to tight tolerances for OE-style fit and function
• 100% inspected for balance and critical dimensions
• GEOSPEC coated for corrosion resistance and a silver appearance

Installation Notes and Tips

Verify rotor style, brake package, and OE rotor design before ordering, especially on BMW 340i xDrive and 440i applications with optional or M Sport brake setups. Clean the hub mounting surface before installation and follow the vehicle manufacturer’s torque specifications. For proper bedding, use a controlled break-in procedure with new pads matched to the rotor surface.
