1.1% the wrong way--decrease in overall gearing and increase in weight. 255 is win/win but no doubt 275 looks better. I ran 225 all the way around for 4 months and the only real difference was looks and the car was noticeably quicker. I think the 's' is overtired from the factory in order to keep people on the roads including the degree of stagger front to back. Sometimes less is more but no doubt bigger looks better.
