What is the benefit of drilled and slotted rotors?

Drilled holes help release heat and moisture from the rotor surface, which can improve braking performance, especially in wet conditions. The slots help to sweep away brake dust and gases, ensuring a cleaner pad surface and more consistent stopping power.

Does this rotor come with any hardware?

This listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately. Please refer to the manufacturer's installation instructions for a complete list of required components.

What is the black coating on the rotor?

The black electro-coating is a protective finish applied to the rotor's surface. It helps prevent rust and corrosion during shipping and storage, and it also gives the rotor a clean, finished look. This coating is designed to wear off in the area where the brake pads make contact during normal use.
