Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed to meet the specific braking requirements of select Audi models. Its vented construction improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The rotor’s surface is both drilled and slotted, allowing for efficient removal of brake dust, gases, and water, which can improve brake pad contact and reduce fade under demanding conditions.

With a nominal thickness of 29.8 mm and a discard thickness of 28 mm, this rotor provides a durable braking surface while maintaining safety standards. The rotor’s 320 mm outside diameter and 52.2 mm height ensure proper fitment and compatibility with the specified Audi vehicles. The zinc silver coating on the hat offers corrosion resistance, extending the rotor’s service life.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a vented design. This combination is intended to enhance heat dissipation and improve braking response, especially in performance or heavy-duty driving scenarios. The silver zinc coating on the rotor hat provides rust resistance, helping maintain rotor integrity over time.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes brake pad glazing and uneven wear
• Prevents rust and corrosion on rotor surfaces
• Restores proper braking function on Audi A4, A5, and Q5 models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify the 5-bolt hole pattern with a 112 mm bolt circle diameter matches your vehicle’s hub. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 631-73057R rotor to meet OEM specifications for fit and function on compatible Audi models. The rust-resistant zinc silver finish on the rotor hat helps extend service life. While no specific warranty information is provided, the product is designed to maintain consistent braking performance under normal operating conditions.
