Just to clarify what I meant by the twist of the bar, I was referring to the relative force on the bar itself. I know that the rotation of the suspension is the same i.e. if the suspension compresses, the lower control arm goes up and it rotates the front end of the bar clockwise. If you switch ends, put the markings in front, the rotation of the lower control arm is still clockwise but relative to the bar, the force is in the opposite direction.
The picture below shows the marked end the bar and the direction of force if the markings are in the Front and what it is if in the Rear. None of this really matters at this point because I am going to install as it came from the factory. Like I said originally, just pondering if it matters. Thanks for the feedback.
