Autogryo, I trust you don't mind my marking up some of your images so that I can explain the whole tangent line thing as I see it.

Your first one:

Your second one:

Here is my car at 30 degrees - approx.

Some other P-Cars:

An old racing Porsche modified with roof line per race rule allowances.

I stand by my earlier statement that 10-15 degrees is best, you can get away with 20 degrees on a good day, and that 30 degrees has air lifting off of it quite easily at speed. I also think the template works and is an "Idea" we should strive for but maybe not marry.
