ET32 OEM Y Spoke Rims on an A8L ?
You would need to say more about intended tire size as well as rim width (which will be stamped on them), but in very general terms that ET will push the rims outward in the fender well around 1/2." Essentially that would substitute for spacers if you want a more aggressive look, and be about the max you would want to do in front (where the likely spacer used is 12-15mm).
This is assuming the rims are at least 8 1/2" width (offsets and rim widths are interrelated when you look at how it fits relative to the fender location); if they are only 8" I probably would pass except for snow fitments. Also, think about wheel strength. If the wheels are from an A4/A5 type class, that is a meaningfully different weight and power car than an A8. S5 maybe--somewhat lighter, but until recently w/ a 4.2. By A6 it is in the same weight class in general, and if a 4.2 A6 then pretty similar power and torque.
