So I was looking at my iQ the other day and noticed that like my xB the front is wider then the rear. I went inside looked it up and found that the front over all is .6 inches wider then the rear. doesn't sound like much but it was bugging me. So since I hadn't put my summer wheels back on my xB yet I decided to do so and use my front spacers from my xB on the rear of the iQ. seeing as the spacers are 8mm spacers the rear stance now matches the front stance. it looks a lot better.
