They look pretty similar, but I only glanced at them quickly. If you want to compare for yourself, check out Aerogear's site and GD 2000's site ...

To see the Aerogear wing, click on a Honda Civic or something, and if you scroll down a bit, it should have a section that says "Hybrid Wing." If not, click on another make/model. I know the '96-'98 Civic coupe section had a picture there.
The manufacturer sites were the only ones I could find pictures of the wings. Couldn't find any other sites that showed a lot of good pics of the Aerogear Hybrid wing.
Sorry.
