Here are some zoomed out pictures to give you an idea of flow...what I like about it, is it's like it was meant to be there.
I've been speed testing it, and on a straight line, I don't realize much stability, but high speed sweepers (95mph+), the rear is more planted when accelerating. I'm loving the aero with this part...def functional. On a track day, I would say would enhance high speed stability (like the last turn on Lime Rock):
