If you were thinking of putting 235/40 18 inch tires on your car. Don't do it!!!!!!!!! There is a guy here in town that has a G2 coupe with that setup. I spoke with him and said that when he turns it rubs like crazy. He said U-turns suck. Just a little FYI (for your information). Stick with the 225/40 18's and of course with a +42 or better rim.
