Has anyone converted the semi-adjustable rear anti-roll bar setup back to the original T-post configuration? Mechanically it is simple, but I'm wondering how the stiffness of the T-post compares to the blade setup. The post comes in two different diameters, 1/2 and 5/8, I have both but I will probably use the smaller diameter one. Short of making some kind of bench-top test rig to measure stiffness, is there any other way to determine how stiff the T-post setup is compared to the blades?
