I think 15s look best on the '65-70 Mustangs, so I'm running Mopar 15x7 black steelies on my '68. 16s look alright on some cars and some 17s are ok on the '71-73s, but "dubs" on any of them don't do it for me.
Did that affect your speedo readings? My car has 205 70 14's right now how much different would that be? I've been thinking about getting some American Racing Vintage torq-thrust D's to put on my car after I get it up-n- runnin.
