Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is a solid disc rotor with a nominal thickness of 12 mm and a discard thickness of 10.5 mm, ensuring reliable service life and safety margins. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The directional surface design further enhances braking performance by optimizing pad contact and heat dissipation.

The rotor’s hat is finished in zinc black, providing corrosion resistance and durability, complemented by an overall rust-resistant coating on the rotor. It features 6 bolt holes and stud/lug holes with a diameter of 13.8 mm, arranged on a 139.7 mm bolt circle diameter, ensuring proper fitment on the Hummer H3 and H3T hubs. The center hole diameter measures 101 mm, and the overall height is 68 mm, matching OEM specifications for these vehicles.

About the DFC Brake Rotor - Drilled and Slotted - Black Product Line
