About the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black product line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor cooling. This design helps maintain consistent brake performance by reducing heat buildup and preventing gas accumulation between the pad and rotor surface. The black zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to dissipate heat generated during braking. The rotor's surface is both drilled and slotted, which aids in removing brake dust, water, and gases, contributing to consistent pad contact and improved stopping power. The rotor has a nominal thickness of 30 mm and a discard thickness of 28.4 mm, ensuring safe replacement intervals. The zinc black finish on the hat provides rust resistance, while the plain disc finish maintains structural integrity. The rotor is directional, designed to optimize braking performance when installed correctly.

Applications and Problem Solving

• Reduces brake fade during high-performance or heavy-duty driving
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust and gas buildup for consistent braking
• Enhances corrosion resistance for longer rotor life
• Restores braking efficiency on BMW 7 Series models with worn or damaged rotors

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle diameter pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 28.4 mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc black coating on the rotor hat enhances durability in various driving conditions. While no specific warranty information is provided, the rotor is designed for reliable performance and longevity when installed and maintained according to manufacturer guidelines.
