I can feel more drag when the car is cold. I had a test on my "bullnose" that demonstrated higher drag when cold (rather than finding the aero effect of the bullnose that I was looking for). Sometimes I think I can hear the rear brakes when cold. Can't say I know for sure.

I'm still debating what to do with the hole on the underside. I believe several ecomodders have left the edge harsh and still had positive results, although I doubt that's optimal... I might split some pipe insulation or large rubber hose into half-cylinders and add it to give the bottom edge a radius, then do a little coroplast to close up the bottom. Surely that would help.
I forgot to mention in my todo; you're right that I need a pair of braces in the middle; I'm pretty sure it bends in the wind. I have a little video camera I can strap to the lower grill temporarily to verify rigidity at speed. That should make for some fun shots too, assuming I manage not to lose my camera.
