If you have any pictures handy I'd love to see a picture of what you installed.
I posted some pictures and details here on the Civic's build thread. I really can't recommend doing what I did due to it not holding on well as well as just not looking the best aesthetically. 19bonestock88's is a much better design.





Didn't you try something similar here with a box cavity once?

I'll have to see if I can find it again, but there was someone on here with a 7th gen Civic coupe who ABA tested a decent improvement with a full box cavity - almost a boattail - at the rear end of the car starting at the trunk lid.

I thought about doing that, but then I used my small amount of available clear plastic to do those mirror boattails I tried out. Another user on here (might've been thedonkeycrx) got pulled over for having clear lexan "obscuring" the taillights on a VX a long time ago, something to keep in mind depending on how strict the police are in your area.
