It is notable that in the previous tests of different underbody air dams the front
rim had been closed!!!

Can it be that "open rim" means the rim types that come OEM?

I wonder , to what extent would rear wheel skirts stand in for the "closed rim?"
I take it that a closed rim is essentially an aero wheel cover.
Wow, that is interesting. Curiouser and curiouser.
