I got them with my new wheels. I have them for about 6 months now and they are working out ok. I think they have pretty hard compounds so they are not the best for track, fine for the street. It takes them a while to warm up, you really have to get up to highway speed for a bit. They hook up ok once warm. The good thing is that the thread life is going to be pretty long, no significant wear yet after 6 months. I don't drive the Z in the rain so I can't tell you how it handles in the wet but the Tire Rack test whos that it handles very well in the wet. Bottom line, because I drive the Z so little I would prefer something a bit more sticky since thread life is not a real concern. But if you drive the Z regularly than the Fuzion is not a bad choice IMHO.
