What is the benefit of drilled and slotted rotors?

Drilled holes help to vent heat and moisture away from the rotor surface, which can improve cooling. The slots help to sweep away brake dust and gas that can build up between the pad and rotor, maintaining better contact for more consistent stopping power.

Does this rotor come with any hardware?

This product includes the brake rotor only. Any necessary installation hardware, such as lug nuts or brake clips, is typically sold separately.

Is this rotor a direct replacement for my factory rotor?

Yes, this R1 Concepts brake rotor is designed to be a direct replacement for your original equipment. It fits the 2004 Subaru Impreza without requiring any modifications.
