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 feature both drilled holes and slots on the braking surface. This design helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape more efficiently. The black zinc coating on the hat area provides additional protection against corrosion, extending the rotor's service life. This line is tailored for drivers seeking a balance between performance and durability in their braking components.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type rotor with a directional surface pattern combining drilled holes and slots. The drilled and slotted design enhances braking efficiency by promoting better heat management and reducing the risk of brake fade during demanding driving conditions. The rotor's nominal thickness is 10 mm, with a discard thickness of 8 mm, ensuring a clear service limit for safety. The zinc black hat finish offers rust resistance, which is critical for maintaining rotor integrity over time, especially in environments prone to moisture and road salt exposure. With five bolt holes and a bolt circle diameter of 112 mm, this rotor is engineered to fit securely on compatible Audi and Volkswagen models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A4 Quattro and Volkswagen Passat
• Improves braking response and reduces brake fade under heavy use
• Addresses rotor corrosion issues with rust-resistant coating
• Helps eliminate brake noise caused by uneven rotor surfaces
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness is within the specified limits (discard thickness 8 mm) before mounting. Use proper torque specifications for the 5 lug bolts to secure the rotor. The directional drilled and slotted surface should be installed following the rotation direction indicated on the rotor to maintain optimal performance.
