So you are basically saying they would somehow fixate the chassis at the suspension mounts which would transfer the suspension loads. Makes sense. So at that point, the car is clamped down at 4 corners, potentially with more than 4 attachment points. I am not sure about the force application. If you were to simplify it to 4 mounting points in the corners, which points and directions are the forces being applied exactly? I can see different permutations resulting in different axis.
