I still have my B6 with has RS4 Replica wheels with a 35mm offset (8x18). The stance is perfect in my opinion and I would like my B8 to look the same.
I tried swapping wheels to see how it would look but unfortunately the RS4 reps do not fit on the B8s hub.
So I took out the ruler and measured as best and accurate as I could.
On the B6, the fronts sit exactly flush with the fender from what I can tell. The rears it ~5mm inside from the fender edge.
On the B8, the fronts sit 14mm inside from the fender edge while the rears sit 21mm inside from the edge.
So to get the same look, I would need 14mm spacers up front and 16mm in the rear. I have not seen either of these sizes so now the question is, should I go with 10mm/15mm...15mm/15mm or 15mm/18mm? 10mm/18mm?
10mm on the front would put the wheel 4mm inside from the fender edge and 18mm would but the rear 3mm inside from the center edge. That sounds pretty good I'm thinking. I don't think I want to do 15mm on the front as it's past the 14mm that would make it flush and I don't want it to stick out one bit.
Here are some photos showing both cars...





I was surprised to see the stock 18" Sport Package offset is ET47! So whimpy! :)

Was also surprised by how nice and thick the Sport Package anti-sway bar is. Looks seriously aftermarket.
