Um, apparently nobody else is noticed this, so I might as well throw it out there... You can do as you like, it is your car, but using a spacer will change the offset of your wheels, which is never a good idea. Your entire suspension is designed around a certain track width (middle of one wheel to the middle of the other), while I could go in depth as to what changing the offset will effect, I think I'll just say it doesn't make your car do good things...especially on the front...
Just my 2 cents...
