Chassis deflection is when done properly aka. resulting in a final number in lbs/ft or more relevant to SI -- newton/meters. You're going to need a constant and repeatable testing scenario first off. Your car will have to be supported on a lift or opposing jack stands and be absolutely level, which is pretty difficult to achieve with jackstands that come with 7-10 height settings. And even then, that will only account for the torsional forces. If you want to test for longitudinal and latitudinal flex youd need to devise a different system. IIRC in the real world, chassis flex is measured by the bare chassis being attached at each bumper frame and then torque is applied and the angle of deflection is measured. And since it is in a free floating system they can measure all aspects of chassis flex. I'm not saying it's not possible, but I don't think that it's repeatable, and therefore not consistent and constant to use as a benchmark test.</blockquote>
