I have found that after fitting Bilsteins, (LRA longer travel models) the gas pressure, lifted the vehicle a little - effectively increasing the spring rate.
As many other changes were made at the same time, I can't comment on how they affected roll, but I would be surprised if the roll stiffness was not increased a little due to the gas pressure.
John, the gas pressure exerts a lifting force (area of shock shaft x gas pressure=lifting force) but it doesn't increase spring rate, it's more akin to increasing spring pre-load, once the initial nose force on the shock is overcome to get the shock moving, it contributes nothing to the spring rate. The nose force itself is more like a stiction in the shock.Quote:
