looks wise the 13's will fill up the opening alot better, performance wise they of course will be better,but unless you are autocrossing etc and want to get the last little bit of everything out of it, the smaller ones will work fine. On a 18 inch wheel the smaller will be ok, but on a 19 or 20 they could look smallsih. I have c5 rears on my 69 with 20's and to me they look little.
