2002 A4 Avant Quatrro wheel change
 

Im looking at getting a set of new wheels. Im hoping to get a staggered set with 8.5" up front and 9.5" at the back. Ive been looking at forums pictures etc but cant find out weather it will fit or not. Ive heard that being a Quattro things might be more difficult to fit for some reasons, but im not too sure. Im looking at stretched tyres aswell if it makes it better. Cars sitting on adjustable coilovers at the moment so can go higher/lower at any time, preferably lower. Im not sure on what offsets will fit or how it all works. Can anyone help me out or give advice, also some pictures or links to some b6 avants with same fitments would be good. Cheers.
