I don't drive that low, that is the parked height, and of course ride height is a few inches higher. As someone else said it is on air struts and shockwaves in the back. As for the bumpsteer, I do have a bumpsteer kit, but it must also be stated that I am running Racecraft drop spindles, so that help me be lower, but not alter the suspension geometry as much like a spring drop would.
