Preferably while still on the car and without any special dynos.
- I have a set I like on the car(Hotchkis) and would like to know how they compare with other setups(Pfadt Street).

For a 4x4, I would probably drive up on a flex ramp/rock and see when the other wheel leaves the ground. But that doesn't go well with a vette.

What about:
1. jacking the car up on one side
2. put another jack under the one control arm.
3. jack up control arm until other side lifts - note height.
4. swap swaybars/change setting and compare.
The spring would be involved and maybe the shocks to some extent, but since they are the same - would not the stiffer bar lift the other sides tire first?

Better ideas?
- Preferably involving less work and time than installing and driving

Or someone already know how Pfadt streets compare to Hotchkis?
- Not in Pfadts table.

Don't really know if I'm missing anything, but I have both and should sell one kit.
Pfadts never installed and the Hotchkis work very well for me - maybe I could go stiffer so if Pfadt ranges from softer to stiffer, they may be the right solution for me.

(stock springs and Bilsteins)

Thanks,

It would be easier to put scales under your jack, and plot displacement vs load.

However, bar stiffness can be calculated by thickness and the length of the lever arm if the materials are the same.

I don't have a car scale, but that would be better and they do use different materials and design. Maybe I should look in to scales.

- Looking at the Pfadt graph, I conclude that Pfadt Street should cover the range from softer to firmer than Hotchkis, if C6Z < Hotchkis < T1.
- But that doesn't help me in picking the same setting as I have
