Torsion Bar Adjusting

Just to give you an idea, from my experience, if you have the heavy duty factory V8 torsion bars (.890), you can easily get away with 1/2 to 3/4 inch of lowering with the adjuster. I chopped off about 3/8" off the top of the bump stop when I went 3/4", but it doesn't really ever hit it in normal driving. This was on my fastback, not the 'vert in my avatar. I dialed down the 'vert about 3/8" to level it out. It has stock slant six springs, and it's possible the rears are a little tired. But it sits nice now, and has plenty of suspension travel, even on rough roads.
