I've got mild, visible sag in the right rear wheel compared to the left. It was this way when I bought the car (1961) twenty years ago. Two well-respected shops I've spoken with have said not to adjust it because the torsion bar will sometimes break if you do. I use the car mainly for long distance driving and don't want to get stuck somewhere, obviously. With all the forum messages indicating people have had no trouble with this procedure, maybe I should ask if anyone has had one break (?)
