I saw some talk about running 11" wide wheels all the way around on an S197. 11" wide wheels require precise offsets to keep from rubbing basically everything, so I took the easy route (since my car is bagged) and went 20x10F and 20x11R.
My rear wheels are 20x11 +53mm. I wanted to see what they would look like up front, so before I mounted the tires I bolted one of the rear wheels onto the front. The 20x11 +53mm fit flat against the front rotor, but the back lip of the wheel just barely touched the strut. So in my opinion, you have two choices if you want to run 20x11 square:
1. +53mm rear and +47mm front. That would give an extra ~1/4" of clearance to the strut in the front.
2. +53mm all the way around, but run 1/4" spacers up front. This way you could rotate the tires front to rear. (this is the option I would choose if I wanted to run 20x11 square)
To help visualize, I'll attach three pictures. First is an angled shot of the rear wheel with the tire mounted and the car aired out onto the tires. Next is the rear wheel bolted onto the front brake. Finally there's a pic of the 20x11 rear wheel bolted onto the front, but at a sharp angle so you can see that there's room to come out (1/4" spacers) without poking out past the fenders.

Since the sidewalls don't stick out past the lip of the rims, 295s on 20x11s will definitely clear in the front. (as long as the car isn't bagged, like mine) I should mention, you can certainly go lower offset than I am recommending. (and it'll rub the fender like crazy if the car is low) But what I suggested will essentially center the tire between the fender lip and the strut.
