Hi Matt,
The sides have been tapered about the same amount all along -- the rear track is ~3 1/2" narrower on each side, than the front. The extra convex on the side windows is done by not tapering it in as quickly.
The frontal area is ~25 sq. ft. and the rear transom is a little under 10 sq. ft.
My hunch about the new nose is that the (apparently) lower stagnant point can help, and if the fenders are going to help wedge the air around the front wheels, then it could help. But, it might add some separation on the sides, and if it is problematic, I'll revert to something like I had before. *Hopefully* I can figure out how to get some CFD done!?
Yeah, the rear license plate is too small...
