that's true.. the handling with a bigger and wider wheel is much better. I have 17" in my actual car (a Mirage LS Coupe.. until i get my new Civic EX Coupe
) and you can actually feel the difference in handling, cornering!, skidpads and all. and besides! they always look much better!!
The one problem is depending on the quality of the roads in your city or town wich can be a headache on bigger wheels or better said thin tires! (40´ or less).
