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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced cooling and debris removal capabilities. The drilled and slotted surface pattern improves brake pad bite and helps maintain consistent braking under demanding conditions. The zinc silver coating on the rotor hat provides corrosion resistance, extending rotor life especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor measures 310 mm in outside diameter and 58.4 mm in height, matching the exact fitment requirements for the specified Audi models. The 5-bolt hole pattern with a 112 mm bolt circle diameter and 15.2 mm stud hole diameter ensures proper mounting and alignment. The directional slotted and drilled surface enhances water and gas evacuation, improving braking consistency in wet or high-performance driving conditions.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Audi TT Quattro, TT RS Quattro, and TTS Quattro
• Improves heat dissipation to reduce brake fade during spirited driving or track use
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust resistant zinc silver coating
• Enhances brake pad bite and reduces brake dust buildup

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or residue prior to mounting. Verify the 5-bolt hole pattern and 112 mm bolt circle diameter match the vehicle hub. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction as indicated by the rotor design.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fit and function. The rust resistant zinc silver coating on the rotor hat helps extend service life. While no specific warranty information is provided, adherence to discard thickness and proper installation ensures reliable braking performance and safety.
