I really don't care for it either. If you want to do something like that, do what spook did, and just use a smaller tire on the front with the same rim size on the front and back. Can't really tell that way, so it looks better.
I'm gonna be puttin' 4 19" rims and tires on in the spring. The tires I got will be 1"-2" smaller in overall diameter than the ones that came on the car (low prof), and therefore, better acceleration!!!
