Detailed Product Features and Specifications
This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that promotes airflow between the rotor surfaces, helping to prevent brake fade during demanding driving conditions. The rotor’s surface is both drilled and slotted in a directional pattern, which aids in channeling away brake dust, gases, and water for improved pad contact and braking efficiency. The rotor’s hat is coated with a zinc silver finish to resist corrosion, extending the rotor’s service life. With a nominal thickness of 20 mm and a discard thickness of 18 mm, this rotor meets precise dimensional standards for safe operation. The rotor features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 66 mm, ensuring proper fitment on Mazda RX-7 models.
