I read through something like that and get to one spot and say WHAT?

In that he says that to keep the body roll down the roll bar is transferring spring from the inside to the outside, holding the inside up and keeping the outside from moving up. OK, got it, so now how does weight get transferred back to inside when the lateral acceleration is throwing it to the outside? Short answer is it doesn't, while every other thing about the sway bars is true it simply can't put weight on the inside tire. In fact it's working to pick the inside tire UP.
