Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is designed to meet the demands of performance-oriented Audi and Volkswagen vehicles, ensuring consistent braking under various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The rotor's surface is both drilled and slotted, which aids in removing brake dust and gases, improving pad contact and braking response. The rotor has a nominal thickness of 30 mm and a discard thickness of 27 mm, indicating when replacement is necessary. The zinc silver hat finish offers rust resistance, maintaining structural integrity and appearance over time. With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor fits securely on compatible Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade during high-performance or extended braking
• Improves heat dissipation to maintain consistent braking power
• Helps prevent brake pad glazing and uneven wear
• Minimizes rust and corrosion on the rotor hat for longer service life
• Enhances braking response on Audi and Volkswagen vehicles such as Golf R and Passat CC

Installation Notes and Tips

Ensure the rotor is installed on vehicles with matching bolt hole patterns and dimensions, specifically 5 lug holes with a 112 mm bolt circle diameter. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness of 27 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and other braking components during rotor replacement for optimal performance.
