I am having trouble finding an 18" wheel (either 18x8 or 18x7.5) for the A3. Something light, preferably less than 24lbs. Anyone know how heavy the stock 16-spoke wheel is?

If you look at our stock wheels (sport or premium package) the front wheels seem to sit more outwards and the rear wheels seem to sit more inwards, when compared to the respective fenders. (Front track is 16mm wider than rear track according to the brochure.) I like my wheels to sit about flush with the fenders, so this makes choosing an offset difficult. See a few with a +45mm offset, but wonder whether this would make the front wheels stick out, especially with a 18x8 wheel.
