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 heavy braking, and can help prevent brake fade.

What is the black finish on this rotor for?

The black finish on this rotor is primarily for aesthetics, giving a clean look behind the wheels. It also provides some initial protection against rust and corrosion.

Does this rotor come with any hardware?

This product listing is for a single brake rotor only. Hardware such as brake pads or mounting bolts are typically sold separately.
