One thing comes to mind,and it's because of my experience with the CRX at Bonneville.
Where the nose pan angles down is an area which is really significant.Even with the full belly pan,we still don't want to encourage any air to go under the car.
Ford used an active air dam on it's Probe-IV,which lowered on the highway to block off this flow.
I made a flexible chin spoiler from polyurethane floor pad from BIG-LOTS which deforms at curbs.It slices the airflow off from the belly pan.And without the pan,I'm still seeing some of my highest-ever mpg.
I think you'd like it if you did it.
Fabulous project! It will be hard to wait on your new mpg numbers.
Thanks.

I originally planned on a NASCAR style bumper. However, time constraints dictated otherwise.

It's on the "to do" list.
