About the DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors engineered for enhanced thermal management and braking consistency. The drilled and slotted surface pattern helps to evacuate gases, dust, and moisture, which can accumulate during braking. The black zinc coating on the rotor hat provides additional corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Detailed Product Description

This vented disc brake rotor is designed to fit Audi and Volkswagen vehicles including the Golf, Jetta, TT, and TT Quattro. The rotor’s 312 mm diameter and 34.2 mm height ensure proper fitment and compatibility with the specified models. The directional drilled and slotted surface improves braking performance by allowing heat and debris to escape, reducing brake fade during aggressive or repeated stops. The zinc black finish on the rotor hat and rust-resistant coating protect against corrosion, maintaining rotor integrity over time. The 5-bolt hole configuration with a 100 mm bolt circle diameter matches factory specifications for secure installation.

Common Applications and Problem Solving

• Reduces brake fade caused by heat buildup during heavy braking
• Improves wet weather braking by dispersing water from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Prevents rust and corrosion on the rotor hat and braking surface
• Ensures consistent braking performance for Audi Golf, Jetta, TT, and TT Quattro models

Installation Notes and Tips

Ensure the rotor is compatible with your vehicle’s make and model before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications for the 5-bolt mounting pattern to avoid warping. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor lifespan.
