There are countless Nissan wings to try out, go to a body kit shop and try em all out till your hearts content, but dont expect them all to bolt up. You need to make new holes for some wings and patch up your old holes or just put washers over them, then put in screws for each hole, bolting them from underneath the boot, just in case you want to use those holes in the future for another wing. Thats what I have done. Unless you have a crazy body kit and your car is lowered, then don't bother.
Even then, I think the dumped look and a good custom rear bar looks good without a wing, like mine. It took me a long time to find a wing that was well suited for my custom look. I only use the GT-wing for track use only. Wings are over rated these days. If its not a real wing, and your not gona use it for racing, it does nothing, don't bother at all.
