Considering unwanted legal attention, I kind of recommend putting the tail length on the tail itself.

As soon as you are (relatively) happy with the performance - fiberglass the cardboard!

Wow. This too is amazing. I only just noticed this thread (I don't have much time for the car anymore).
You are incredible. Seriously. What a funky idea for "fun and edutainment." 
Subscribed. Can't wait to see those tests.

Um, you're saying the car weighs 1075 pounds?
It weighs ~2,700 pounds, so 43 pounds is 1.6%. |

Thanks for the compliments --- it doesn't look as nice in person as it may in these photos! (Mostly due to wrinkly shrink wrapped plastic.)

Nah. I'm likely only keeping the car a couple more months, and nobody else is going to stick this on an 8th gen. Civic.
To ensure it lasts for the duration, here's how it stays out of the weather when not in use...
Used boat shrinkwrap. Boat tail prophylactic!
Still waiting for good testing weather. |

The pocket behind the tail lights is like a small,sideways notchback car section.The air separates at the edge of the 'cliff',then reattaches as it would on an extended boot/trunklid.
There is a local recirculation bubble and the tufts are dancing within this turbulence.
You do pay a minor penalty for the turbulence,but with reattachment,the outer flow skips over the localized disturbance and goes on as if it didn't exist.

Would you have a picture of the view from the inside? Maybe with the boattail and with just the Kammback.

I know. I keep seeing it and thinking it's very symmetrical from the side view.

Will do. I'm going to be away for the next 5 days or so, so I'll get that when I return.
It's actually a good, functional window -- and the view is the same with the tail on or off (can't see the tail through it.) In case you're wondering, the back part of the Kamm isn't clear. Just the panels on the top surface.
