This is my first A4, a 2006 non Quattro. The previous owner lowered it with Koni springs and shocks. While they are supposed to be adjustable, haven't been able to do so yet, the ride is too harsh for my liking. It corners great but... I'd like to return it to stock so if there is anyone interested in a swap I'll give up the parts for free if need be. I appreciate any help given.
