Well I am ready for new rims and tires on my 06 GT. Currently I have the stock 17's on the car. I'm wondering about the pros and cons of the different sizes (e.g., 17's vs 18's). I'm thinking I want all corners the same width and height but not sure what size rims to go with. I know 18's look better, but is there any advantage to having the larger rim? I'm most interested in good handling.
