What is the benefit of drilled and slotted rotors?

Drilled holes help heat and gases escape from the rotor surface, while slots sweep away dust and moisture. This combination can lead to more consistent braking performance, especially under heavy use.

Does this rotor come with any hardware?

This listing is for a single rear left brake rotor. Hardware such as lug nuts or brake pads are typically sold separately.

What does the black finish mean?

The black finish is primarily for aesthetics, giving the rotor a clean look behind the wheel. It does not affect the braking performance of the rotor itself.
