THe question that should be in this discussion is: Is there any torque reaction that could lift the rear of a car through a trailing arm or is the car lifting from the wheel/tire trying to "drive under the car" ,pivoting around the front pivot and causing the lifting action? Probably still not stated correctly for you but I'm pretty sure you know what I mean.
We are on the same page anyway. I'll concede this technically you are correct but in the practical application I am.
