Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor cooling. This product line is designed to reduce brake fade and maintain consistent stopping power under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life on Audi vehicles.

Technical Specifications and Features

This disc brake rotor features a vented design with a 321 mm outside diameter and a 46 mm overall height, allowing for effective heat dissipation during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases and debris from the brake pad surface, improving contact and reducing brake fade. The rotor is directional, meaning it is designed to rotate in a specific direction to maximize performance. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion over time. It includes five bolt holes with a 112 mm bolt circle diameter, compatible with the specified Audi models. The nominal thickness of 30 mm and discard thickness of 28 mm ensure the rotor maintains structural integrity and safety throughout its lifespan.

Compatible Audi Models and Common Applications

• Replacement rotor for Audi A4 and A4 Quattro brake systems
• Suitable for Audi A6 and A6 Quattro models requiring vented rotors
• Fits Audi Allroad Quattro for enhanced braking performance
• Compatible with Audi S4 for improved heat management and braking consistency
• Addresses issues such as brake fade, rotor warping, and corrosion

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the 112 mm bolt circle diameter and use proper torque specifications for the 5 lug holes. Inspect the brake pads and calipers for wear or damage during installation to maintain optimal braking performance. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 28 mm.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on compatible Audi models. The rust-resistant zinc silver coating helps extend rotor life by preventing corrosion. While specific warranty details are not provided, the rotor is designed to maintain structural integrity and braking performance within the specified thickness limits.
