I wouldn't even consider the 235/45/17 size. The thicker sidewall would take away steering response and the larger diameter would make acceleration more sluggish with the taller gearing.

Oh, and with the PSS, I would recommend running lower pressures than stock for better grip. 31 or 32 psi is working well for me.
I don't think I am going with 235's, but if I did, I think they would be 40 series - I'd have to run it through the calculator to see if that worked. I wouldn't want a taller tire.

Leaning towards 225/45 at the moment. (ok, I realize this might be taller than a 215/45 on a 7" wide wheel, maybe, but it would be as tall as I'd want to go.)

Won't be doing track days or autox. If I ever decided to, I'd get a separate set of wheels/tires.
