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 to improve brake pad bite and heat dissipation. This design helps reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life, especially in environments prone to moisture and road salt.

Detailed Product Description

This solid disc brake rotor is specifically designed for Audi A4 Quattro and Volkswagen Passat models, ensuring compatibility and reliable fitment. The drilled and slotted surface improves water and gas evacuation from the braking surface, which helps maintain effective braking in wet or high-temperature conditions. The rotor's nominal thickness of 10 mm and discard thickness of 8 mm provide clear guidelines for maintenance and replacement, ensuring safety and performance. The zinc silver hat finish offers additional protection against rust, which is critical for longevity. With five bolt holes and a bolt circle diameter of 112 mm, this rotor aligns precisely with the vehicle's hub assembly.

Common Applications and Issues Addressed
