Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is engineered with a vented rotor design that improves heat dissipation during braking, reducing the risk of brake fade. The rotor surface features both drilled holes and slots, which help to evacuate gases, dust, and water, maintaining consistent brake pad contact. The directional surface type is designed to optimize braking performance when installed in the correct orientation.

The rotor’s hat is coated with a zinc silver finish to resist rust and corrosion, extending the rotor’s service life. The disc itself has a plain finish, providing a smooth braking surface. With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor meets the necessary safety standards for replacement. The 4 bolt holes and stud/lug hole diameter of 12.75 mm ensure proper fitment on compatible vehicles.
