Or is this even possible? Please post pics. Thanks!

nope.... i like your avatar though.... very nice.....

thanks i modeled/rendered it myself...

i havent seen any...........i would think its too small

A G rear spoiler was put on a Z with alittle of professional tweaking by a body shop and it looked awesome.

i dont think it will work unless you cut that spoiler. Reason being the trunk shape on the Z is a lil bit more rounded off in the middle that the G. But hey anything is possible.

I think it will look good as well.

im not too big a fan of any spoiler, but the z spoiler caught my eye, because it is simple and clean
