Are you going to cover the hood raise foam and the tail foam with something? More fiberglass perhaps?

I think it would be fun to setup a hidden camera in your driveway to get
peoples responces of your CRX as they walk by from walking their dog..

When I get out there, I'll road trip and we'll have to paint the town foam LOL

just curious, how old are you? looks like you've done this before..

I'm modifying a model of your CRX with some modifications done to it.
I'd like to run some CFD tests on it to find an optimal shape.

Here is what I was thinking you could do to the tail :

The extentions that are behind the rear wheels could be sectioned so as to straighten the turbulent flow from the wheels. Also, there could be channels and extentions that not only act as a diffuser, but would be angled inward to 'pinch' the airflow into a tighter wake pattern.

tested it up to 75mph already without the rear quarters on .. all stayed there just fine, realize its all fiberglassed over when done

OK new Pics of the roughed out tail.. there will be boat tails behind the tires and as seen in the above 3d drawings the center section will be higher than the tire tails.
