Since my stock rims have failed me im in the market for some aftermarket ones which got me thinking. Staggering the width from the front to the back makes perfect sense, but why not stagger the size of the wheel aswell. Having a 17 on the front would preserve things like the speedo, cornering and breaking and then 18's on the back to fill the arches and because they usually are available in wider widths. I know there are several supercars that use this setup but im not sure if it would unbalance the zed which wasnt designed for it and its a rather expensive lesson to learn. I cant see any downsides to it other than trying to buy such an unusual set of wheels and i think it might give the zed a more aggresive stance on the road but if it unbalances the car than its pointless. Anyone have any thaughts?
