Well these are 17*8 43mm so i dunno if different brands will fit different http://www.iwsti.com/forums/1812387-post1223.html
doesn't mean anything unless you are buying that exact wheel. spoke design is what dictates whether or not a wheel in a given size will fit (as in, 1 8" +43 wheel might clear and a different 8" +43 wouldn't)
So now if these fit http://www.iwsti.com/forums/1721502-post1100.html the same brand but in something like a 18 would fit as long as the width was the exact same right?
yes... post #21 of this thread is 17x8 +48 wedssport sa-90. The sa-70 is a nice wheel also. the 17x9 fn01r-c's with 255/40 tires would look really nice.
