If there is a better area to ask this question, point me to it. I have a stick 55 series 1 3100. I was wondering about possibly going with 17 x 7 front and 17x9 rear. No idea what backspacing would be needed and what size tire to go with. She is stock now, but have been toying with the idea of a 2" drop.

I appreciate any feedback.
