A quick video mock up using what I had at the house that shows the direction of thinking. It's not perfect, but demonstrates the principles involved. It's pretty clear the endplate is one of the primary functioning elements* and it's downward movement helps leverage the wing assembly into its nose high attitude via the pivot point on the swan neck wing mount and the pivot point on the endplate where the secondary flap mounts. *A revised thought: yes, the endplates move downward, but the contributor isn't the endplates themselves but the cheese wedge/diffuser/engine cover is compliant to allow aero loading to drive them downwards. Flexible bodywork, and flexible in a direction that I'm sure they're never tested in. For more on Toyota's rear wing see:
