OK, Joe, I agree with you, and I am tring to find 2 more 18" stock wheels for the same reason. I called kaoautostyling and they said they would keep their eyes out for some, since I already bought from them.
But you also will have to do this:
You will have to buy the valve stems from D/C that send the tire pressure to the monitor included with the garage door closer buttons. They cost $45.20 each - P/N 5096808-AA-SENSOR TI 8037155
This assumes you want the tire pressure sensors to work on your winter tires as well. The only pain in the butt with this is that when you change your tires back and forth, you have to make a trip to the dealer to reset the sensors to your car. They hook up the computer and it reads each sensor when a magnet is placed on it. It only takes a few minutes, but depending on your relationship with the dealer, you may be charged for the time. I was not charged for the reset on the winter tires, but I will have to wait and see if they will do it twice per year for free...
Here are a few other places to check for wheels:
transwheel.com 800-892-3733
hubcaphaven.com 877-482-4283
I found these sites when I was doing my search. They had wheels for the Crossfire, but the center caps were listed as an optional item.
