What other GM factory wheels fit? For instance, will the Cobalt SS wheels fit? I assume the G6 and Aura wheels fit but what else fits no modification? Buying used wheels on ebay can be a cheap way to get a different look and have an extra set of rims for snow tires.

Any 5-110 bolt pattern will work. Most all GM cars have the same wheel offset, so just about any 16-18" GM wheel you can find will fit provided it's 5 lug.
