I can't answer your question for the OEM set-up. When I installed the 235's on the front, I had already installed Eibach Springs, Koni Dampers, AMG sway bars front and rear and adjusted the camber & caster...
I can tell you that I ran the car on the track with the OEM set-up with only 800 miles on it and was immediately disappointed with the handling. It PLOWED through the corners and had alot of body roll. I immediately went on a mission to re-tune the suspension. I then ran it with new suspension with the OEM tires and it was really good, not perfect but...
What I'm saying is, a bit wider tire is not going to make the noticeable difference that you are hoping for. It really is a suspension thing with this car... For $1,000 you can make it handle like a dream, with $1,800 you can make it handle like a pseudo-racecar... And still keep the same tires...
