Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented Audi vehicles, offering a balance between durability and effective braking under various driving conditions.

Technical Specifications and Features

This rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The directional slotted and drilled surface enhances water and debris evacuation from the rotor face, improving wet-weather braking performance. The rotor’s nominal thickness is 33.9 mm, with a discard thickness of 31.5 mm, ensuring a clear maintenance threshold. The zinc silver hat finish provides rust resistance, maintaining structural integrity and appearance over time. The rotor features five bolt holes with a 112 mm bolt circle diameter, compatible with the specified Audi models.

Applications and Problem Solving

• Improves braking performance on Audi A6, A6 Quattro, A7 Quattro, and A8 Quattro vehicles
• Reduces brake fade caused by excessive heat during aggressive driving or towing
• Minimizes brake noise and vibration through precise manufacturing and surface design
• Helps prevent rust and corrosion on rotor hats for longer service life
• Enhances wet-weather braking by channeling water away from the rotor surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 31.5 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 112 mm bolt circle diameter). Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures the 631-73064L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver finish on the rotor hat helps protect against corrosion. While specific warranty details are not provided, Dynamite Friction products are generally backed by quality control standards to ensure reliable performance on Audi A6, A6 Quattro, A7 Quattro, and A8 Quattro vehicles.
