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

The drilled holes on the rotor surface help to vent gases and dust away from the braking surface. They also aid in dissipating heat, which can lead to more consistent braking performance, especially under heavy use.

Does this brake 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.

Should I replace both rear rotors at the same time?

Yes, it is standard practice and recommended to replace brake rotors in pairs on the same axle. This ensures balanced braking performance and prevents uneven wear.
