That's a very nice car. The drivetrain is from Mercedes, is it not? Please don't cover it with coroplast.

What's the use case? Race? Commuter? Show car?

You could possibly push it well below 0.30, but what is working against you is called fineness ration, IOW it's short and stubby. jeff88's overlay doesn't show any extension at all. A complete boattail would be approx. as long as the wheelbase of the car. So it comes down to how much 'pain' you can tolerate.

I'd leave the car completely stock and add a single wheel trailer like BamZipPow's, but finished to a level to match the car.

Else you could consider a hitch mount like HHOTDI:

He saw a positive benefit dragging around a brick. Imagine what an aeropod would do.
