What is the benefit of drilled brake rotors?

Drilled rotors have holes that help to vent heat and gases away from the braking surface. This can lead to more consistent stopping power, especially during hard braking or in wet conditions.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Any necessary installation hardware, such as lug nuts or brake pads, would typically need to be purchased separately.

What does the black coating on the rotor do?

The black E-coating is a protective finish applied to the rotor's surface. It helps prevent rust and corrosion, especially during storage and initial installation, and maintains a clean appearance.
