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 braking efficiency and rotor cooling. This product line is designed to reduce brake fade and maintain consistent stopping power under demanding conditions. The silver zinc coating on the rotor hat provides additional protection against rust, making it suitable for vehicles exposed to varying weather conditions.

Technical Specifications and Features

This solid rotor features a 285 mm outside diameter and a 58.4 mm overall height, fitting vehicles with a 5-lug bolt pattern and 114.3 mm bolt circle diameter. The rotor’s 14.5 mm bolt hole diameter and 71.3 mm center hole diameter ensure precise fitment. The directional slotted and drilled surface helps channel away heat and brake dust, improving pad contact and reducing the risk of brake fade during extended use.
