I'm curious on how I might go about testing the differences between two sway bars. Obviously there is only so much scientific data one can record just from driving the car. I understand the engineering of the bar to a certain degree, i. e. Hollow versus solid, distance of mounting points away from the bar, wall thickness, material. But aside from scanning these bars into an engineering system and running tests / simulations, is there any way that I can actually test the difference between two bars?
