The reason that I ask, is that I see that even in your sketches, you have a lot of flat sides and sharp angles.
I'm assuming that you are going to smooth those edges right ?

I'm sure that you know this, but the angles that you have now will result in two huge vortexes ( corkscrews ) of air at the rear of your car.



The rear of the tail should have rounded edges ( similar to my first illustration ) versus being a boxy shape. The red lines in the picture above show the path that air will take in your current configuration. The black lines are what we are after.
It is basically just a tapering of the shape that proceeds it.
Thanks again for your input!!!

Yeah the pics I have posted are very square to the actual layout. In fact I test fitted a side panel and the way it attaches the whole back will be a cone shape like your black lines of your sketch.

Thanks on the advice of the back panel I will have to come up with a smoother shape instead of the one on my drawing.
