?Is this a Bump-steer? If so, what is the cause?
A change in toe during compression is bump steer, front or rear. The cause is the change in relative lengths of the tie-rods and lower control arms between the chassis and the hub.

Rear toe-in during cornering would slow rotation because it puts the rotation point behind the car, rear toe-out puts the rotation point inside the chassis making the rotation faster.
