Designing the Satchell Link

[Norm Peterson]

In some way a low roll center would be better because you can use your sway bar to tune it better. If you have a high roll center and very little body roll then minor changes will make a big difference.

That's pretty much the way it works. Springs and bars (and shocks) can only tune the handling based on the amount of roll that occurs. With a high RC and not much roll, it takes much greater changes in the spring and bar stiffnesses to achieve a given handling change. When the suspension gets really stiff, you start losing a lot more of your tuning efforts to chassis flex unless you go back and stiffen that, too (not as easy as you might think, BTW). Never mind what happens to the ride.
