Product Line Details: DFC Geoperformance Rotor - Drilled and Slotted

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 reduce brake fade by allowing gases and heat to escape more effectively during heavy braking. The directional surface pattern is engineered to maintain consistent contact with brake pads, improving overall braking response for vehicles such as the Audi A1 and Volkswagen Golf.

Technical Specifications and Features

This disc brake rotor features a solid construction with a nominal thickness of 9 mm and a discard thickness of 7 mm, ensuring durability and clear replacement guidelines. The rotor’s surface is finished plain, while the hat is coated in Geospec silver grey, providing corrosion resistance. The rust resistant coating extends the rotor’s service life, especially in environments prone to moisture and road salt. The rotor includes 5 bolt holes with a 100 mm bolt circle diameter and a center hole diameter of 65 mm, matching the factory specifications for compatible Audi and Volkswagen models.

Applications and Problem Solving

• Replaces worn or warped rotors on Audi A1 and Volkswagen Golf models
• Improves braking performance by reducing heat buildup and brake fade
• Addresses rotor surface cracking and glazing through drilled and slotted design
• Prevents rust and corrosion that can compromise braking efficiency
• Restores proper rotor thickness for safe and effective braking

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 100 mm bolt circle pattern. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Follow manufacturer torque specifications when securing the rotor to avoid warping. The directional surface requires correct orientation during installation to function as designed.

Quality Assurance

Dynamite Friction manufactures the 830-74019R rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and precision machining contribute to consistent braking performance and extended rotor life. While specific warranty details are not provided, Dynamite Friction products are generally backed by quality control processes to ensure reliability in compatible Audi and Volkswagen vehicles.
