Rear tire fitment

Does driving habbits play a roll? I cant imagine it moving more that 1/2" if the set up is tight? do you drive like Mario Andretti

Just my thoughts.

When one leaf compressed the distance from the front mount to the center of the perch gets longer, ( flattening a curve in the spring)

And

On the other end unloading the spring on the other side does the reverse.

The combination would result in a slight turning of the rear axle. Enough to be noticable ??????
