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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking efficiency. This design helps to reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Details and Specifications

This solid rotor features a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring a clear maintenance threshold for safety. The rotor's directional surface, with both drilled holes and slots, is engineered to optimize braking performance by allowing gases and dust to escape, reducing the risk of brake fade. The rotor fits Audi A4 and A4 Quattro models with a 5-lug bolt pattern and a 112 mm bolt circle diameter. The center hole diameter measures 68 mm, and the stud/lug hole diameter is 15.5 mm, matching factory specifications for proper fitment.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Audi A4 and A4 Quattro
• Improves heat dissipation to reduce brake fade during aggressive or repeated braking
• Helps prevent rust and corrosion with zinc silver coated hat finish
• Enhances braking response with slotted and drilled surface design
• Maintains proper braking performance with solid rotor construction

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the 5-lug 112 mm bolt circle diameter pattern on your Audi A4 or A4 Quattro. Use proper torque specifications for lug nuts to avoid rotor warping. 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 fit and function. The rust resistant coating on the rotor hat enhances durability in corrosive environments. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry standards for quality and reliability.
