Details on the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a black zinc finish on the hat area. This product line is designed to provide enhanced braking performance through improved heat dissipation and debris removal, while the black zinc coating helps protect against corrosion. The 633-73031R rotor exemplifies these features, making it suitable for Audi S4 drivers seeking a balance of durability and performance.

Technical Specifications and Features

This disc brake rotor is vented to allow air flow between the rotor surfaces, which helps reduce heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, aids in channeling away gases and dust generated by the brake pads, improving contact and reducing brake fade. The rotor has a nominal thickness of 30mm and a discard thickness of 28mm, ensuring a clear maintenance threshold. The rotor’s hat is finished with a zinc black coating to resist rust, complementing the rust-resistant coating on the rotor surface itself. It includes 5 bolt holes with a 112mm bolt circle diameter and a center hole diameter of 68mm, matching the Audi S4’s specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped Audi S4 brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion on rotor surfaces for longer service life
• Addresses brake noise and vibration issues caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the 5-lug, 112mm bolt circle pattern specific to the Audi S4. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-73031R rotor to meet or exceed OEM standards for fit and function on the Audi S4. The rust-resistant coatings and zinc black hat finish contribute to the rotor’s durability. Warranty information is available through the manufacturer and should be consulted for specific coverage details.
