Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is engineered with a solid rotor design featuring a drilled and slotted surface type. The drilled holes and slots help to dissipate heat and gases generated during braking, reducing brake fade and maintaining consistent performance. The rotor’s nominal thickness is 10 mm, with a discard thickness of 8 mm, ensuring a clear maintenance threshold for safety. The rotor hat is coated with a zinc silver finish to resist rust and corrosion, extending the rotor’s service life.

The rotor is directional, meaning it is designed to rotate in a specific direction to maximize cooling efficiency and braking response. It features five bolt holes with a 112 mm bolt circle diameter, matching the factory specifications for Audi A4 and A4 Quattro models. The overall height and center hole diameter are precisely engineered to ensure proper fitment and alignment.
