A6 S-Line wheel offset?
Next, offset is not something one simply decreases until wheels fit. Changes to offset change steering geometry. Keep that in mind. Going 5-10mm is OK, but more is not so good an idea.
3rd offset is only part of the issue - spoke shape is the other. So there is always some trial and error.
First find out what calipers you have. Not HP2? No problem for 16s.
