DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking efficiency. This design helps to reduce brake fade by allowing gases and heat to escape more effectively during heavy braking. The directional surface pattern is engineered to maximize pad contact and maintain consistent performance under demanding conditions.

Detailed Product Description

This disc brake rotor features a solid construction with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring durability and safety throughout its service life. The rotor’s surface is both drilled and slotted, which aids in heat dissipation and helps prevent brake pad glazing. The directional design improves water and debris evacuation, maintaining braking performance in various driving conditions. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance along with a rust resistant coating on the disc surface to extend the rotor’s lifespan. With five bolt holes and a bolt circle diameter of 112.1 mm, this rotor is designed to fit securely on compatible Audi and Volkswagen vehicles.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves braking response in wet or slippery conditions
• Prevents brake pad glazing and uneven wear
• Minimizes rust and corrosion on rotor surface
• Maintains consistent braking performance for Audi A3, Volkswagen Jetta, Passat, and Tiguan models

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s specifications. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.
