I am not a mechanic but I was underneath my H2 the other day and was looking at the design there and I don't think by adjusting the torsion bars you are raising the body. You are actually rotating the "A" arm down towards the ground which in turn raises the body. But at the same time you just rotated your tire at the same time, thus requireing adjustment to the tire for proper camber.
