Factory ride height?

Thanks for the advice. I want to baseline the car now and try to get the same height when I'm done.
I don't quite understand the bit about the 1.03 torsion bars "lowering" your car.

The PST have the torsion bar hexes clocked differently thus lowering the car when installed correctly.

My concern is the back end being jacked up from stiffer HD springs or the front being too low from using the wrong torsion bars. Supposedly PST is working on 1.03" bars with factory style hex orientation.
