wheel fitment question E34

[Wcsco123]

so im thinking about buying a set of staggered wheels 17x8.5 ET11 FRONT and 17x10 ET5 in the rear...

will I be able to run such a wide rim in the rear without any mods to body etc..?

car is stock height.

You might need to roll your arches, can't remember off the top of my head, but I think E34 arches are a lot bigger than E36's.

I took some measurements etc. and I looked under and saw what looks like an already rolled fender. Must have been a previous owner at some point. I'm hoping to get away with a 275/40/17 tire in the rear
