Compare Mair's torpedo with Hucho's teardrop.
Here're examples of fitting the (admittedly squashed and stretched) teardrop, with it's truncations, to the body above and below the beltline, separately:
You could consider a Kammback/boxcavity for the greenhouse (for sightlines) and a truncated teardrop for the tail.

70%
after the rear tires?! Umm, that can't be road legal if I add that much to the rear of the car... lol.
I could not find Mair's torpedo. Do you have a picture?
That is an idea! I am curious to know what kind of drag reduction I would get with a setup such as the one you describe. I would hope for less than 0.20 Cd.
I made some *epic-fail* front skirts today. I am embarrassed to post them, they are that bad
I am doing coast down testing tonight! We will see just how much improvement I have done to the ZX2. Stock Cd is 0.33, I am hoping for >0.3
I will be using the method spelled out here ->
Measure the drag coefficient of your car
