The thing about splitter function in general is that it works on the pressure difference between damming up airflow on top of it (high pressure) and keeping the airflow as laminar and fast as possible underneath (low pressure). The further out in front it extends and the further back under the front it extends, the more effective it will be. All the ones pictured in this thread so far will do something, but they are far from being as effective as possible. Of course, a maximized splitter is not too practical on the street. But maybe some of these can be modified to accept a bolt-on extension (in both directions) for track use, which can be quickly removed for street use.

AJ Hartman Aero is a guy that actually does testing and research on the devices he sells. Unfortunately, I don't think he's done anything for Camaros yet. He will do custom parts, though.
