They were lower than the OEM wheel which ended up on the car.I thought I might have posted that comparison.I'll dig it out.

Thanks Phil. Found it.

The baseline for this test seems to be an "open wheel." I seriously doubt that the improvement would be anywhere near that great if the Insight wheel were used as a reference. It is by no means "open."
Still, I like the moons and will give them a try. Already drilled and threaded my "worst" set of Insight wheels
