I posted this on the fest' as well...

They should bolt up right? Since I ordered the 20's stock, I am thinking of mounting the snow's on some e39 size wheels. A 19 x 8" wheel with a 15mm offset would have about the same amount of "tuck" that the factory 20 x 10" with a 40mm offset right?

10" = 254 mm / 2 = 127mm center - 40 mm offset = 87mm mounting face to outer lip

9" = 228mm / 2 = 114 mm - 25mm offset = 89 mm mounting face to outer lip

8.5" = 216mm / 2 = 108 mm - 20mm offset = 88mm mounting face to outer lip

8" = 203mm / 2 = about 102 - 15mm offset = 87mm mounting face to outer lip.

Does this make sense? Am I way off? I was looking at getting something in the 19 x 8.5 or 9" wide with the similar offset's.

What do you think? They are the only other BMW with a 74.1mm hub right?
