If my car didn't come with HIDs and i buy used rx8 ones will i need any special things to make them work? I've tried searching so don't flame me to much. thanks

I would image just hard wiring the ballasts and mounting them. I would check the service manual to check the specifics.

Yeah, youll need the bulbs, holders and ballasts along with the projector housings.

Will headlight leveling be an issue?

it's very easy to adjust

search for posts by me, I installed an aftermarket set.... Its pretty straight forward.
