Accepting the fact that 20" wheels look better than the 19's...... the question is what does it do to the ride? I'm about to replace tires and wheels on my 2015 S5 Cabriolet and it's decision time. How much ride comfort, or how noticeable is it when you move from 19's to 20's???? I've already followed the forum's advice and upgraded the air intake, performance chips, suspension, sway bars, Catback exhaust, etc.... time for some new shoes! So what size do the experts recommend?
