It is hard finding any aftermarket stuff for this car, that doesnt reek of junk. i have been planning on upgrading to some 20's, but i agree it is definitely hard. if you go on discountedwheelwarehouse.com they have a ton of packages and one of those visualizer things to see the wheels on your car. I was thinking about getting the Arelli Geneva's. i saw them in a car magazine and thought they would look awesome with my tribeca.
