Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. The rotor’s surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving stopping power. The nominal thickness of 22 mm ensures durability, while the discard thickness of 20 mm indicates when the rotor should be replaced to maintain safety and performance.

The rotor’s hat is finished in zinc black, providing corrosion resistance and a clean appearance. Additionally, the entire rotor is coated with a rust-resistant layer to extend service life. With 5 bolt holes spaced on a 100 mm bolt circle diameter and a center hole diameter of 65 mm, this rotor is designed for precise compatibility with specified Audi and Volkswagen models.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

Installation Notes and Tips

Ensure the rotor is installed on the correct side, as the directional slotted and drilled pattern is designed for specific rotation. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 100 mm bolt circle diameter pattern. Clean the rotor surface before installation to remove any protective coatings or residues. Check rotor thickness regularly and replace when reaching the discard thickness of 20 mm to maintain optimal braking performance.
