i went to the local wheel specialist to look around and see the available wheels for the bimmers. i told the sales person that i was looking for different kinds of wheels but i basically wanted to get 18x8.5 all around. the sales person was trying to get me to purchase 9.5 for the rears since i will be getting 18's. won't the 9.5 for the rear stick out?? i have seen 9 width and they almost were flush, but i haven't seen 9.5. i am not sure if i want wider wheels for the rear, but i do know that i don't want them to stick out. should i stick with the 8.5?
