dropped spindles?

The spring rate is linear. Meaning the force required to go from 1" to 2" of travel is the same additional force to go from 2" to 3" of travel. The rate of change is the same. Of course it takes more and more total force as the spring is pushed.

It's just following the elastic curve on the materials tension graph. In the elastic region the curve is flat and the rate of change is constant.

Okay, that's basically what I said, but with a bit more detail. So, what is the "elastic region" of these torsion bars? I doubt it's very much since the bars themselves don't twist very much.


PS: BTW - I remember reading your page some years ago when you were apparently in the midst of deciding whether to go with a bigger front A/S bar and add a rear one, or stay with only the front A/S bar of smaller dimension. What made you finally decide to go the former route ... pure performance numbers, better driveability, better transitions, what?
