I'd like to get something more aggressive looking for my new ride but I haven't found a good source for fitment data. The car will be a garage queen and already has stiff suspension, coil overs and lower ride height. I'm replacing a set of original narrow Fuchs. Here's my questions:
1) 17" or 18"?
2) recommended rim and tire width front and back
3) Required back spacing

I'd like to find a set of used CCW, Fikse or like wheels but I need to know what to look for. Would these work - 18x8.5 et 50, 18x10 et 54, 235/40 fronts, 265/35 rears

Sorry for all the questions and thanks for the advice in advance.
