Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that promotes airflow between the rotor surfaces, helping to prevent brake fade during extended use. The rotor’s surface is both drilled and slotted in a directional pattern, which assists in channeling away brake dust, gases, and water for improved pad contact and braking efficiency. The rotor hat is finished with a zinc black coating 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 four bolt holes with a 100 mm bolt circle diameter, matching the Mazda Miata’s factory specifications for straightforward installation.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish.
