Awesome job, Tribone! Major props to you and your efforts.
I really like the spoiler on that Carbon Creations car... it looks a lot like the SLP ZL575 spoiler except with maybe more pronounced corners. I think I might e-mail them and see if they'll produce it.
I also like the style wings on the Classic Design Concepts, the white/orange pace car, and the black car... except those splines on the back of them. I think they'd work better without em'.
