One thing to consider; the wings on the ROAR legal bodies are cut down substantially, if they were to be kept higher, they would give greater downforce. Other than that, the Can Am/Lola bodies are good, but they aren't sedans. People have tried to use the Saleen, especially on nitro when running at club level, but I haven't heard that much to comment on. I have heard the truck bodies actually work pretty good, but that's not speaking from personal experience.
