From your photo it looks like the new tail brings the car out to 56% of Template aft-body.
At this length the data curve predicts Cd 0.1625.If we throw back in a 3.3% deviation it gives a drag coefficient for your car on the order of Cd 0.167.

How long is the template aft body? Could you estimate the Cd with the length of the aft body at 100%, 87.5%, 75% 62.5% 50% etc?
So people can see exactly what can be gained by adding another foot to their car. I'd like to know what length is needed to go "all out" and adjust for what i'm comfortable with. Maybe people would go for a complete aft body if they knew what it required and the benefits over a short Kammback.
