The 'standard' wheel is 7x18 et 43; the next is 8.5x19 et 36; and then 8.5x20 et 36
So if you use 9x20 et 35 almost the entire extra half inch (except the skinny mm) of width over the 19s or 20s that Audi use, will be split evenly inwards and outwards, from the upmarket (19-20) wheel. So you can figure about a 1/4 inch each way ... that help?
