I bought Replika R198 19x8.5 et 25 square setup. They have the correct bolt pattern and 66.6mm hub bore. Will move the wheels out 5mm front and back, don't think it will be noticable. I originally went for 9.5" rears, but they won't fit a 255 tire, apparently winters at 255 are 7-9" wheel.
We are pretty limited on wheel options that don't require sacrificing our first born to the Bavarians.
For tires I went with Michelin Latitude Xi2 235-55-19, 255-50-19. They are 1.3-1.7% larger diameter than the stock 21s.
