I have the 17x8.5" ET40 ARC-8s (E36 fitment) and I think they work out pretty well. I run 245mm-width tires and am lowered. Rear fenders are rolled a little, but the result is zero rubbing, even when loaded or during rapid weight transfers during AX.
I mean, I get that a wheel with an extra 1/2" of width and chassis-specific offsets would be better, but in the absence of perfect, there is at least a pretty workable solution.
