Dynamic Friction 7004-31103 Disc Brake Rotor Set - Front and Rear

Performance brake rotor set

Dynamic Friction 7004-31103 is a drilled and slotted brake rotor set built for drivers who want OE-spec fitment with added braking response. It fits 2003-2008 BMW Z4, front and rear, and is engineered for consistent stopping performance in everyday and wet-weather driving.

Key features

• Drilled and slotted design for stronger pad bite and improved wet-weather braking response.
• Slots help clear brake dust and road debris while reducing pad glazing.
• Drilled holes help reduce heat buildup across the rotor surface.
• G3000/G11H18 cast iron construction for durability and stability.
• Non-directional finish supports faster, more even pad bed-in and smoother stops.
• Machined to tight tolerances and inspected for balance and critical dimensions.

Detailed description

The Dynamic Friction 7004-31103 rotor set combines performance-oriented drilling and slotting with OE-spec engineering. The castings are machined to tight tolerances, finished for even pad contact, and inspected to meet critical quality targets. For BMW Z4 applications, this rotor set provides a direct replacement option that balances braking response, heat management, and everyday drivability.

DFC Rotors-Drilled and Slotted-Silver is the product line behind this part number, focused on performance brake rotors with a silver finish and a design that supports cleaner pad contact and stable braking behavior. If you are replacing worn rotors on a BMW Z4, 7004-31103 offers a fitment-specific solution with performance-focused rotor geometry.

What it is used for

• Reducing brake fade from heat buildup during repeated stops.
• Improving initial pad bite in wet or damp conditions.
• Clearing debris that can interfere with rotor and pad contact.
• Addressing vibration or uneven braking caused by worn rotor surfaces.
• Restoring braking consistency on BMW Z4 applications.

Installation notes and tips

Fits 2003-2008 BMW Z4, front and rear. Verify rotor dimensions and brake system configuration before installation. Clean the rotor surfaces before service and follow proper pad bedding procedures after installation to help achieve even contact and quiet operation. Part number 7004-31103 should be matched to the vehicle application listed above.

Quality assurance

DFC states that these rotors are inspected for balance and critical specifications after machining. Dynamic Friction also backs this part number with a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
