Thats the most important part IMO.
There was some discussion about which way slotted rotors should face. Brembo recommended a certain way, but plenty of other sources said the opposite. I think the concensus was that it didnt make a huge difference.
I think the direction of cross drilled rotors matters much less. They are usually drilled in a directional pattern, but if slotted discs can go either way, I'd say drilled discs can too.
