Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented design to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade. The rotor features a plain disc finish combined with a zinc silver rust-resistant coating on the hat area, enhancing durability and corrosion resistance over time.

With an outside diameter of 325 mm and an overall height of 89.2 mm, this rotor fits vehicles equipped with an 8-lug bolt pattern and a bolt circle diameter of 165.1 mm. The center hole diameter measures 118.1 mm, and the bolt hole diameter is 16.5 mm, ensuring precise fitment. The rotor’s directional brake surface is designed to optimize braking efficiency and pad wear.
