Hi all, I had a set of H&R springs fitted to my A3 S Line,sportback quattro recently but they seem to be softer than the standard springs. So I'm thinking about fitting a set of Bilstein B4's. Are these in anway upgraded over the standard shoxs. I'm sure I read somewhere that they are a little stiffer. The mileage is 85000 so the standard shoxs are probably past their best.
