Hi all, you may have read my earlier post about returning to an A4. My new car is a 2003 2.5v6 convertible sport. Our other car is an A3 sportback 2.0tdi 170 quattro s-line, I would like to improve the suspension on the A4, I know it is never going to handle like the A3 but is there an easy way to tighten it up a little? Can you use later s-line springs? Or would I have to down the lines of a full handling kit?
