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 improve brake pad bite and heat dissipation. This product line is designed to reduce brake fade and maintain consistent braking under demanding conditions. The 830-74019L rotor exemplifies these features with its solid construction and rust-resistant coating, making it suitable for daily driving and spirited use on compatible Audi and Volkswagen vehicles.

Detailed Product Description

This disc brake rotor features a solid design with a nominal thickness of 9 mm and a discard thickness of 7 mm, ensuring a long service life before replacement is necessary. The rotor’s slotted and drilled surface helps evacuate gases, dust, and water from the braking surface, which improves braking response and reduces the risk of brake fade. The directional surface pattern is engineered to optimize braking efficiency and pad contact. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rust-resistant coating further protects the rotor from environmental damage, extending its operational lifespan.

Compatible Vehicles and Common Applications

• Replacement rotor for Audi A1 and TT models
• Suitable for Volkswagen Beetle, Golf, Golf City, Jetta, Nivus, Polo, and T-Cross
• Addresses issues such as brake fade during heavy use
• Helps reduce brake noise and vibration
• Improves heat dissipation for consistent braking performance

Installation Notes and Tips

Ensure the rotor is installed on vehicles with a 5-lug bolt pattern and a 100 mm bolt circle diameter. Verify the center hole diameter of 65 mm matches the hub for proper fitment. It is recommended to inspect brake pads and hardware during installation and replace if worn. Proper torque specifications should be followed to avoid rotor warping. The directional surface requires installation in the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 830-74019L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and durable construction contribute to long-term reliability. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
