it's the Drifter II front bumper w/ '99 cav Drifter-style side skirts modified to fit the cobalt

 

this is one more that I found but I dont like the angle that it's drawn

 

The first drawing is awesome. How come the kits don't look just like that

 

Well that first drawing was done by, i guess some sort of civil engineer (forgot his name) because that was his only automotive drawing, he also had a concept for the Twin tower memorial and other completely un-related stuff. So the point that i'm getting at is that the Grip Kit and the drawing could be completely unrelated , but that would be a Huge coincedence and I doubt that they r unrelated. So your just gonna have to ask the boys at Grip- why they arent the same.

P.S- I like the drawing much better too
