Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide consistent braking performance while resisting rust and corrosion, thanks to its zinc silver coating on the rotor hat. The vented rotor design further aids in heat dissipation, making it suitable for daily driving and moderate performance needs.

Product Specifications and Features

This disc brake rotor features a vented design with a directional surface that includes both drilled holes and slots. The drilled and slotted surface helps to evacuate gases and debris from the brake pad contact area, improving braking response and reducing the risk of brake fade. The rotor measures 296 mm in outside diameter and 51 mm in height, with a nominal thickness of 30 mm and a discard thickness of 27 mm, ensuring durability and longevity within specified wear limits.

The rotor hat is finished with a zinc silver coating to resist rust and corrosion, extending the rotor's service life. It includes five bolt holes with a diameter of 16.3 mm arranged on a 120 mm bolt circle diameter, compatible with vehicles such as the Buick Regal and Saab 9-5. The center hole diameter is 67.4 mm, matching OEM specifications for proper fitment.
