Dynamite Friction 7004-31030 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotors

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31030, are performance brake rotors built for BMW applications that call for front and rear rotor replacement. The drilled and slotted design is aimed at improving initial pad bite, helping shed heat, and clearing debris from the braking surface.

These rotors are a fitment-based choice for BMW 230i, 230i xDrive, M240i, M240i xDrive, 430i, 430i xDrive, 328d xDrive, 330i xDrive, 328i, 428i, 428i Gran Coupe, and 428i xDrive applications across the listed model years.

• Drilled holes help reduce heat buildup during repeated braking
• Slots help remove brake dust and road debris from the rotor face
• Non-directional finish supports faster, more even pad bed-in
• GEOSPEC coating is engineered for OE-style durability and stability
• 100% inspected for balance and critical dimensions
• Vented rotors are electronically mill-balanced when required

Product Details
