Edit- Do not install a belly pan like this covering the exhaust. It is a bad idea.Quick update, I cut holes in my belly pan for additional cooling and reinstalled most of it, I posted more details and pictures in my belly pan exhaust heat related thread. The back middle pan may still need more work, should know by tomorrow. I also got some better pictures of the car now that it is wingless.
Well after I get some of my other projects wrapped up, I am considering a small boat tail type extension out the back of the car. I really like what MetroMPG did on his insight, especially leaving the rear tail lights visible. My car follows AST2 pretty closely, and has close to a 36% “Boat Tail” on it already in side view. I don’t want to make the car extremely long, and it looked like it would be a 24” extension to get to 50%, making the whole car 20” or 12% longer counting the bumper already protrudes.

I was considering a “top only” extension which would extend the roofline to follow the template, but would curve down and stop between the tail lights. A 16” top only extension would only protrude 12” and would take me from 35% to 45%. Would this make enough of a difference to even consider?
