i know theres erebuni, black widow and i dont know the others
i just wanna see how they look

Only two. Stillen and Erebuni. The black widow is custom and not bolt on.

Who has it on their 4th gen? Do you have picture at all the different angle? I know it's a custom job and I have friends that probably can duplicate the install. But i'm thinking of the skyline II type for my car. It's fiberglass so it easy tu cut and put back together.
