• 5 bolt holes with 112mm bolt circle diameter
• Nominal thickness of 22mm and discard thickness of 20mm
• Overall diameter of 300mm and height of 36mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that promotes airflow between the rotor surfaces, helping to prevent brake fade during extended use. The rotor’s surface is both drilled and slotted in a directional pattern, which aids in channeling away brake dust, gases, and water for improved pad contact and braking efficiency. The rotor’s hat is finished with a zinc silver coating to resist corrosion, extending the rotor’s service life. With a nominal thickness of 22mm and a discard thickness of 20mm, this rotor meets precise wear limits to ensure safe operation. The 5-lug bolt pattern with a 112mm bolt circle diameter matches the Audi S4’s factory specifications for a direct fit installation.

About the 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 in a directional pattern to optimize braking performance and rotor longevity. This product line is designed to provide enhanced heat dissipation and improved pad bite, making it suitable for drivers who demand consistent braking under various driving conditions. The silver zinc coating on the rotor hat adds a layer of rust resistance, which is particularly beneficial for vehicles exposed to moisture and road salt.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping and cracking through vented design
• Prevents rust and corrosion on the rotor hat
• Maintains consistent pad contact with slotted and drilled surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify the 5-lug bolt pattern and 112mm bolt circle diameter match the vehicle’s hub. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-73032R rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc silver finish on the rotor hat helps extend the rotor’s lifespan. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure durability and reliable braking performance for Audi S4 applications.
