Thanks for the help! However it appears those wheels don't fit the S13 in 17" but do fit it in 18". I really don't think I want to go to 18's but that's just me.
You bring up a good point though in width. I'm beginning to question my original thinking because it seems that 7" wheels will not provide tires much wider than I have now. So I have to wonder, what's the point in 215/45/17's over 195/60/15's ? About half an inch... that's all. Anything wider requires a wider wheel than 7" (according to Yokohama).
There is the reduced sidewall I realize which helps cornering I'm sure and makes her a wee bit "sexier" but I wasn't really after either.
