You need ET38 or lower to avoid rubbing on the strut which is why all those people with ET42 or ET45 wheels have small spacers. You will also need 2.0*+ of camber and a fender roll. It fits, but it takes a little work.

Some people claim to not need the fender roll. I think ride height plays a factor in this...

The reason why ET45 is a popular offset is because you need a higher offset in the rear. 17x9 ET45 might rub on the outside fender a bit. Again, ride height and camber dependent. If you want to keep rear camber in check at like 1.5-2.0* you might need to roll the rear fenders to fit a meaty 255. Or, run a higher offset wheel in the rear. Problem with that is that the track width difference starts to impact handling characteristics.
Tire size will be 255/35 or 255/40 - I'm leaning on 18s purely for aesthetic reasons. It looks like a 5mm spacer will likely be needed with anything ins the 40-45ET.

It will be DD with about 2* camber, or 2.5* if I can tolerate it.
