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

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction offers rotors with enhanced surface features including drilled holes and slots arranged directionally to improve water and gas evacuation during braking. The zinc black 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 requiring reliable stopping power and heat management.

Technical Specifications and Features

This rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during extended use. The directional drilled and slotted surface improves pad bite and helps maintain clean contact surfaces by channeling away dust and moisture. The rotor’s nominal thickness is 24.8 mm with a discard thickness of 23 mm, ensuring a long service life before replacement is necessary. The zinc black finish on the hat section offers rust resistance, while the plain disc finish maintains consistent braking performance.

Applications and Problem Solving

• Improves braking performance on Audi A4 and A5 models equipped with disc brakes
• Reduces brake fade caused by heat buildup during aggressive driving or towing
• Helps prevent rust and corrosion on rotor hats for longer durability
• Minimizes brake dust accumulation and water interference for consistent stopping power
• Addresses uneven pad wear and vibration issues with directional surface design

Installation Notes and Tips

Ensure the rotor is installed on compatible Audi models listed to maintain proper fitment. Verify the bolt hole pattern (5 holes, 112 mm bolt circle diameter) matches the vehicle hub. Clean the rotor surface before installation to remove any protective coatings or residues. Follow manufacturer torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to optimize braking performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards for fit and function. The rust resistant coating and precision machining contribute to consistent braking performance and durability. While no specific warranty information is provided, this rotor is manufactured to meet the demands of Audi A4 and A5 brake systems, ensuring reliable operation when installed correctly.
