It really is too bad that they don't allow for smooth under-bodies and rear diffusers...you would have a venerable guided missile if they did.

Ok I will leave these for now then, thanks for the info.
Really finding aerodynamics very interesting, bought a few books on it which I am reading at moment.
Well as for the smooth under-bodies, we can have a belly pan, and there is a flat pan under the greabox area too. I will try to find a photo...
Found a photo. Its a crach of another car but gives an idea of the underside.
