Torsion bars and lower control arm set-up

Are you talking about the height adjusters or the LCA pivot nuts?

Most guys advocate final tightening of the LCA pivots when the car is on the ground, has been "jounced" and sitting at ride height

The adjusters about all you can do is "start somewhere" and see what you have for height. Most guys seem to want to adjust them when jacked up/ weight relieved
