The rotor surface is both drilled and slotted in a directional pattern, which aids in removing brake dust, gases, and water from the contact surface, improving braking consistency. The rotor has a plain disc finish and a zinc silver coating on the hat to resist corrosion and extend service life. With a nominal thickness of 20 mm and a discard thickness of 18 mm, this rotor meets precise wear limits for safe operation. The rotor features four bolt holes and lug holes, each with a 13 mm diameter, arranged on a 100 mm bolt circle diameter, ensuring proper fitment on the Mazda Miata hub. The center hole diameter is 55 mm, and the overall height is 45 mm, matching OEM specifications.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Silver Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern to optimize braking performance and rotor cooling.
