but do we know that its built for fe(reduced drag) or could it be a compromise design that is there for stability/downforce at high speed. the chart that shows the aeromods they did and the corrosponding cd advantages does not even list the rear decklid.could a "uglyback" at the top of my rear window work in synergy with the deck extention by attching flow sooner? then i could angle the decklid slightly downward and not have to make it 3 feet long that would allow the decklid to still reattach flow and angle slightly downward creating a smaller rear area to the drag, as well as not blocking my view as much. yes it would not look as cool (but im not trying to pick up chicks ,,,its an echo!
as soon as i get a design that works i will cut and weld some aluiminum plate for a perminant one .
