Greetings to all. I was just wondering if any of you could provide me with some insight. I am looking to get some 18" rims for my Koup EX and I'm sure some of you already have. If so, did you notice any difference in the vehicle's handling, steering, etc.? The wheel wells on these Koups are pretty tight as it is so I wasn't sure how getting 18" wheels would affect it or even fit well. Thanks.
