The rotor features a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during heavy braking. The surface is both drilled and slotted in a directional pattern, which aids in removing brake dust, gases, and water from the contact area, improving pad bite and reducing the risk of brake fade.\u003c\/p\u003e\u003cp\u003eThe rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a clear service life indicator for replacement. The hat section is finished with a zinc black coating to resist rust and corrosion, extending the rotor’s lifespan. The rotor includes five bolt holes with a diameter of 14.6 mm and a bolt circle diameter of 120 mm, matching the OEM specifications for secure fitment.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Black Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine enhanced cooling and debris removal features with corrosion-resistant finishes.
