From the highest part of the car, I come back xx inches, and down yy inches.

If my car is 45 inches at the highest point, what are xx, yy, bb, and cc to be "safe".

For a project as intense as building a whole car, I think you would want to buy a copy of Hucho's "
Aerodynamics of Road Vehicles" the "Bible" of so many on this site. I got a copy through ILL and photocopied key chapters I needed. With all the details you will want to consider, including stability, I imagine it would be very useful to have for ready, authoritative, reference. I think the rule for the slope after the point of highest camber in the roof is 11-14 degrees. The first generation Insight supposedly had both that angle and the taper about perfect for a production car. You could do worse than to imitate it, I imagine.
