DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on a vented disc design. This configuration improves heat dissipation and helps reduce brake fade under demanding conditions. The zinc black hat finish adds corrosion resistance, extending rotor life. This product line is tailored for drivers seeking enhanced braking performance with reliable durability on compatible BMW models.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor surfaces, which helps maintain cooler operating temperatures during braking. The drilled and slotted surface design aids in removing brake dust, gases, and water from the contact area, improving pad bite and reducing the risk of glazing. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.4 mm, ensuring safe replacement intervals. The rotor measures 348 mm in outside diameter and 81.7 mm in overall height, fitting precisely on the specified BMW models. The zinc black coating on the hat provides rust resistance, helping maintain structural integrity and appearance over time.

Applications and Problem Solving

• Restores braking performance on BMW 745i, 745Li, 750i, 750Li, 760i, and 760Li models
• Reduces brake fade during high-temperature braking conditions
• Improves water and debris evacuation from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.4 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the 5-hole, 120 mm bolt circle diameter pattern. Use proper torque specifications for the 16.8 mm diameter lug holes to secure the rotor. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fitment and performance on BMW 7 Series models. The rust-resistant zinc black hat finish contributes to long-term durability. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry standards for quality and reliability.
