W/o me knowing all the technical jargon, I'm gonna need a picture to understand what you're talking about.

The way I had it explained to me, as the LCA pivots, the further away from 0* horizontal it gets, the faster the suspension geometry "gets bad", i.e. if you pivot from -1* to +1*, things are better than if you pivot from 0* to +2*. Even though it's a 2* delta in both cases, +2* is worse than +1* for screwing up the geometry, which is why everyone recommends lowering the car no further than a horizontal LCA at static ride height.

Now, I don't know the details as to why things get worse, so I can't really back up what I'm talking about, but it sounds pretty good to a non-ME like me. If the dynamic camber change is really a linear function of LCA angle, and not as I described it, then it sounds like the handling issues w/ going super low aren't actually due to the dynamic camber change.
