What is the purpose of the drilled holes on this rotor?

The drilled holes help to vent gases and heat away from the rotor surface. This can lead to more consistent braking performance, especially under heavy use.

What does the black coating on the rotor do?

The black electro-coating is applied for corrosion resistance. It helps protect the rotor from rust and environmental damage, maintaining its appearance.

Is this rotor sold individually or as a pair?

This listing is for a single rear left brake rotor. You will need to purchase a separate rotor for the rear right side of your vehicle.
