This is a good post, Earl. I'm thinking this through: side link height is not about roll center, roll center is all at the center pivot...
It's an adjustment I've never bothered with, so I'll admit I hadn't really thought it through at any length, but what you're saying is contrary to what I've heard before.
I remember some Euro racer grinding and lowering side link balls on his 12R5, and the word was he was adjusting roll center. Misinformed? Throwing competitors off the scent? Or is there a more general confusion of roll center with rear steer? It does something, so let's call it roll center!
