Just bought an '02 Allroad. I understand this car requires wheels with 57.1mm Centerbore and an offset of 25mm. I am looking at buying used wheels off a 2013 A6 (66.1 centerbore, 39mm offset) Would this be a mistake on my part? I understand dealing with the offset difference and the need for 15 or 20mm spacers. Is this going to be a pain in my *** to deal with the 66 to 57 center bore as well?

Advice please.
