It wasn't the testing that did in the front skirt. Here's what we talked anout at the Salt Flats Cafe. At least what I got done before Wings3D locked up. It replaces the top hinge with a 4-bar arrangement.

Yes,this was the original plan.The panel would move as on a parallelogram.
What has scared me off from it is all the impact loads from expansion strips,non-flush manhole covers,and potholes.With the extra pivot points the things might be destroyed unless extremely low mass and robust pivots with tight clearances.
I've done carbon fiber and I really like it.To justify it I'd have to do two master plugs (both sides),pull a mold off that,then layup some pre-preg,bag it,and autoclave it.
Since I don't do that sort of thing all the time,it would mean a tremendous investment in time to do it right.And I'd have to build an autoclave with vacuum capability like we used in school.
To properly do all the tooling and produce a single carbon part the size of a loaf of bread required about 240-man-hours.And that's just a bare part with no 'finish.'
