What is the benefit of drilled brake rotors?

Drilled rotors have holes that help to vent heat and gases away from the brake pad surface. This can lead to more consistent braking performance, especially under heavy use.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Any necessary installation hardware, such as mounting bolts or clips, is typically sold separately.

What is the black finish on the rotor for?

The black finish on the rotor is primarily for corrosion resistance during shipping and storage. It helps prevent rust from forming before the rotor is installed on your vehicle.
