question
 

Does anyone know if, or how much harder it is to drift in an FC that has no power steering? I'm planning on removing a lot to reduce weight, and the power steering is most likely one of them.

Another thing, how much worse is it to drive the car without A/C?

well, my car doesnt have power steering, and I can get her sideways and hold it there. And I never use my A/C, as long as you're moving, its not that bad with the windows down. Stop and Go traffic kinda sucks, but hey thats the price you're gonna pay.
