I've just noticed they closed the wheel arch holes. It's a weird hybrid of regulations and technical freedom - which I just don't understand. Why limit themselves to part of a rule set but then make up other bits??! I guess they had a base car which they could bolt bits onto... perhaps that answers my own question...
