Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is specifically designed to meet the braking demands of Audi A4, A4 Quattro, A6, A6 Quattro, A8, and A8 Quattro models. The rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The drilled and slotted surface enhances water and gas evacuation, improving brake pad contact and performance under various driving conditions.

The rotor’s plain disc finish combined with a zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. The rust-resistant coating further protects the rotor from environmental elements, making it suitable for daily driving and demanding conditions. With a 5-lug bolt pattern and precise dimensions, this rotor ensures a secure fit and compatibility with the specified Audi models.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive or prolonged braking
• Improves braking performance in wet or humid conditions by evacuating water efficiently
• Minimizes brake noise and vibration through directional slotted and drilled design
• Prevents rust and corrosion to maintain rotor integrity over time
• Ensures consistent brake pad contact for smoother stopping power

Installation Notes and Tips

When installing the Dynamite Friction 631-73044R rotor, ensure the rotor is mounted with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify that the bolt holes align with the vehicle’s 5-lug pattern and 112 mm bolt circle diameter. It is recommended to inspect brake pads and hardware during installation and replace any worn components to maintain optimal braking performance.
