Agree with some comments here, suspension and height are a major factor, along with the offset of the wheels you are wanting to fit.
DanRSturbo fitted Momo Arrows to his car which only come in 7.5" wide and has a 30mm drop in his suspension and he has no problems at all, except when 4 people are in the car. I was impressed with that.
As for handling, I thought fitting my MO's made my car handle better than with S2 wheels on.
