FOr the front, I had the idea of adding a nose on. The length is a bit much, but I wanted to relax the angle going to the hood. The black on top of the hood is the "platform" to shorten my windshield. I do think it may cause visibility problems if the height is too much.
Here is a link to a new sheet of MPG calculations using the Aero & RR tool. I have adjusted it to theoretical numbers that will come to pass... one day  I put in numbers that would reflect having lost weight, having Potenza's, lowering, complete aero mods, lean burn, turbocharger and a manual transmission. I would be ecstatic if I could really break 125 mpg between my usual 45-50 mph

When Hucho was at Volkswagen,he tried different noses on the Golf/Rabbit.
The upper 'ideal' nose had no lower drag than the lower 'optimized' nose.Again,once the rounding is enough,you're done.
Consider these two cars with identical drag coefficients
