DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide improved braking efficiency through enhanced heat dissipation and reduced brake fade. The drilled and slotted surface pattern helps evacuate gases and debris, while the vented rotor design supports consistent cooling. This rotor line is suitable for performance-oriented applications and daily driving on compatible Audi models.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface improves pad bite and helps maintain clean contact surfaces. The rotor has a nominal thickness of 30 mm and a discard thickness of 28 mm, ensuring safe replacement intervals. The hat section features a Geospec silver grey finish, and the entire rotor is coated with a rust-resistant layer to extend service life. It includes 5 bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 68.2 mm, matching factory specifications for the listed Audi models.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves heat dissipation for consistent braking performance
• Helps prevent rotor warping and uneven pad wear
• Maintains braking efficiency in wet or debris-prone conditions
• Compatible replacement for worn or damaged rotors on Audi A4, A6, and S4 models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle diameter pattern on your Audi vehicle. Proper torque specifications should be followed to avoid rotor distortion. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and precision machining contribute to durability and reliable braking performance. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry quality controls to ensure consistent product reliability.
