Thank you for all the explanations aerohead!
freebeard, I will plan out this 4-bar design while I am on vacation this week. I won't be back till Sunday or Monday.
The wheel skirts failed beyond miserably
As soon as I turned onto the road, the back fell off the rear tab and it was in contact with the sidewall for 1/2 a mile, aluminum rod and all. If I had done my 4 mile test, the tire would have blown out!
It turned out that the hinge is flexing and not keeping the skirts within its tolerances. So this idea is done, and I will be driving to the beach with my same 0.269 Cd lol.
