Detailed Product Features and Specifications

This DFC Brake Rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The drilled and slotted surface pattern aids in expelling gases, dust, and water, contributing to improved brake pad contact and reduced brake fade. The rotor’s directional surface is engineered to optimize performance when installed in the correct orientation.

The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring a clear service limit for safe operation. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life, while the plain disc finish offers a smooth braking surface. With four bolt holes and a 100 mm bolt circle diameter, this rotor fits securely on compatible Audi and Volkswagen models.
