Gary Fast makes some sweet resin bodies for the MegaG/G+ and he has started to mold bodies for the Jag Hobbies PR-5, only one as of this writing.
These bodies are much more realistic and lower profile than the Tomy/AFX/RaceMasters bodies most of us run. They come in a kit that consists of multiple pieces and the rear wings are attached by glue or adhesive to the rear loop of the chassis.
