Dumb question....

But it affects what the spring was for.
On 4 corner scales, loading the torsion bars more or less affects the cross weight or rear loading at stationary postion... like the when leaving the line.
Well, it's not a race car, and to tell you the truth I didn't know any better 13 years ago when I did all that work! Alignment guy must have "fixed" it for me with the torsion bars.
