I wonder if the tires shedding their rubber onto the rear wing affects the aero on the wing?

Side to side is affected by the horizontal elements, because once you're in yaw, the airflow is no longer straight but arriving in a curve. Say for example you have a 3 degree angle on the end plate, but your car is turning at 4 degrees per second, now the airflow is grazing the inside of the end plate, and the outside now has a different profile. This doesn't even consider boundary layer effects. Meaning the physical shape your eyes see is not the same shape that the air sees at speed. This is because the skin friction creates a stationary boundary layer which alters the flow path.

I did not think it would make much difference on a car. Makes more sense for an airplane. I guess they do go pretty fast though.

It's huge, because not only does that area have a force acting on it, it also interacts with the wing and the beam wing which is pulling air out of the diffuser. There's 40 odd points worth of downforce just in this area right here.

There's almost no outwash in that region at all, and it would dramatically improve things to boost outwash in that region.

Triangular nozzles have the strongest jets because they produces the strongest vortex rings.
