What's a manatee? Hope they aren't endangered, because I'm still trying to figure out the dark art of suspension tuning.
Going back to the setup, it appears that the coilovers are such that I have a spring perch adjustment on the upper half of the coilover that allows me to run a longer stroke without affecting the overall height, which is controlled by a separate collar on the lower half of the same coilover. At least that's what I'm been told about how it works.
I'm going to have to go back to speak to the guys who did my corner balancing (same guys who run the Radical Cup) as well.
My bad for not mentioning this before, but the bottoming out happens on the rear, not the front, and there are no marks on the tires, indicating that it is not hitting the arches. Rather, it feels like the shock bottomed out, and again, I am not able to confirm this without further investigation.
