New shocks have an offset spacer tube permanently inserted in their lower mount hole. The tube sticks out one side more than the other, so depending which way the tube is turned, the spacer can be put on the outboard or inboard side of the shock. In this video at 4:50, the spacer is shown placed inboard of the shock, between the shock and the bolt head. http://www.youtube.com/watch?feature...&v=o-pyqyd1h20 And that is the way that I installed my Sensen shocks: http://i49.photobucket.com/albums/f...3 Related/Z3 Jacking/IMG_2408_zpsb190bad6.jpg However, a photo in the Bentley Manual shows the spacer on the outboard side of the shock, between the shock and the trailing arm. But the photo is just to point out the bolt that must be removed. What is the correct orientation of this spacer tube on the mounting bolt? Is the shock mount supposed to be close to the trailing arm, or cantilevered out from the trailing arm by the spacer? Does the incorrect orientation, whichever that might be, cause a misalignment of the shock in the upper mount, or a bending force on the bolt in the lower mount?
