I noticed that the Mustang IROC mod comes with the official mod template. It looks solid.
We may be able to create a standardized paint scheme for everyone on the roster. We'd allow drivers to select colors and numbers. The rest, of course, would be identical. We might need to intervene if everyone wants a black car, like what always seems to happen in our main series.
Does this sound like a nice idea? We'll probably make the driver registrations optional, but you'll need to register to get a driver paint scheme.
