Using many of the ideas presented by the community for inspiration I came up with the following solution for a front anti roll bar. The goal was to allow for adjust ability as well as a linear a spring rate as possible. No i am not an engineer so I don't have any fancy software to validate if this will work, however I am happy with how it travels through the range of motion as well as the ability to adjust the rate.

The way it is setup now it will allow for 109 to 139 lbs of force at 5 degrees of twist with 10 increments in between. The link is just a piece of black pipe I used for mock up. Ill replace that with a proper link as soon as I can find one I like.

a few pictures.
