Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed to meet the specific braking needs of Audi and Volkswagen vehicles such as the Golf, Jetta, TT, and TT Quattro. Its vented rotor design allows for efficient heat dissipation during braking, reducing the risk of brake fade under demanding conditions. The rotor surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall stopping power.

The zinc black hat finish provides additional protection against rust and corrosion, extending the rotor's service life. With a nominal thickness of 25 mm and a discard thickness of 23 mm, this rotor maintains structural integrity while ensuring safe replacement intervals. The 5-bolt hole pattern with a 100 mm bolt circle diameter matches the factory specifications for the listed Audi and Volkswagen models, ensuring proper fitment and installation.
