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

The DFC Brake Rotor - Drilled and Slotted - Silver line from 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 design further aids in cooling, making it suitable for vehicles that require reliable stopping power under varied driving conditions.

Product Specifications and Features

This disc brake rotor features a nominal thickness of 18 mm and a discard thickness of 16 mm, ensuring a clear maintenance threshold. The rotor’s overall height is 68.1 mm, with a center hole diameter of 106.1 mm. It includes six bolt holes and stud/lug holes, each with a diameter of 14.5 mm, arranged on a 139.7 mm bolt circle diameter. The rotor surface is directional, combining drilled holes and slots to help evacuate gases and debris, which can improve braking response and reduce brake fade.

Compatible Vehicles and Applications
