Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented design to improve airflow and reduce heat buildup during braking. The rotor features a drilled and slotted surface pattern that helps evacuate gases, dust, and water, maintaining consistent brake pad contact. The zinc black hat finish provides corrosion resistance, extending rotor life, while the rust-resistant coating further protects the rotor from environmental damage. With a nominal thickness of 25 mm and a discard thickness of 22 mm, this rotor meets precise wear limits for safe operation. The 5-bolt hole configuration with a 100 mm bolt circle diameter ensures compatibility with specific Audi and Volkswagen models.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine functional surface treatments with protective finishes. This product line is designed to provide enhanced braking performance through directional drilled and slotted surfaces, while the black zinc finish on the rotor hat offers improved corrosion resistance. This rotor is part of that line, tailored for vehicles requiring both durability and effective heat dissipation.

Compatible Vehicles and Common Applications

• Replacement rotor for Audi A1 models requiring vented, drilled, and slotted rotors
• Suitable for Volkswagen Beetle, Golf, Jetta, and Polo with 5-lug bolt pattern
• Addresses issues such as brake fade due to overheating
• Helps reduce brake noise and vibration caused by uneven rotor surfaces
• Improves braking performance in wet conditions by channeling water away

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 22 mm. Properly clean the rotor surface to remove any protective coatings before mounting. Verify the 5-bolt hole pattern and 100 mm bolt circle diameter match the vehicle hub. Directional rotors must be installed with the correct rotation direction for optimal performance. Use appropriate torque specifications for lug nuts to avoid rotor warping.
