Hi,i've recently bought a 1.9 tdi 110 avant and been thinking of fitting 18" rs6 wheels on it. Just wondering could someone advise me as would they fit fine with no rubbing or would i be better of on 17's. Would audi tt wheels fit or is the pcd different? Also i think it would need lowering to look at it's best would 40mm do the trick and be fine for everyday use? thanks for any info.
