Default Based on RS6

You can fit 19x9 et29 all around. Best size and offset that fits without rubbing.

You can fit 19x9.5 in the rear, also et29, but the tire will look a bit more stretched. I fit one of these in the RS6 with 295 wide tires.

Front I would not go wider than 9.

18x8.5 and 19x8.5 you can get the same et29, but et24 is the best in my opinion, as it gets the wheel's outter edge closer to the edge of the fender.

I have no experience with 8" wide. However, I would recommend something around et20 to et24.

Please keep in mind that if you have any big brake kits in the car, you also have to inquire if the wheel clears big brakes. The offset is only part of the issue, especially the front wheel, and you decide to go with wheels that have lip. Wheels with lip tend to have flat spoke design, and can be quite an issue to find the right front wheel.

Good luck. Your fenders are the same as the RS6, so values stated should work for you.
