I just got 17x7 VRS wheels with 205/40-17, 5 spoke black with polished lip(my car is white) fits perfect, no rubbing, don't stick out too far, grips like crazy, handling is better, uses a little more gas since I have more rolling resistence, and it still leaves room for lowering. I think u could go 18x7 but they are hard to find. 18x8 would need spacers to prevent rubbing and unless u plan to put a 'lip' in the fenders they would stick out to far and u would not be able to lower it. To me the set I got is the best choice.
