Adjustable upper control arm opinions.

Thank you posting this, it's a lot to process and think about. What you said about trying to prevent rolling by using heavier sway and torsion bars really stood out. Theoretically it would work, but it would make the car miserable to drive on the street. To be honest, I'm considering going down in torsion bar size for that reason.
A bigger T bar will not give a harsher ride when combined with the right shocks. On the Dart I went up from .92s to the 1.03s, combined with Bilsteins, and the car handles the best it has in the 12+ years I've owned it. I also boxed the LCAs, added PST solid tie rod adjusters, adj strut rods, and welded in SFCs. The ride isn't harsh at all.
