Welshy, i meant the binding occurs only at near or full shock stroke, with the arms parrallel, you will not notice any binding. whether you place the hingepins in the inner or outer hole, the binding will happen on the rib on OT-16 knuckle, at full shock stroke. but if you place the hingepins on the inner hole, you get additional caster, and also the c hub rubs a little on the inner part of the arm, becuase of its angle. look at the 3 pictures i attached. you can see the c hub tends to touch the arms the further in they go. and notice the angle the hub is pivoting at, that gives it the caster.
to test the effect on your car, you probably need to disasemble the upper link, and the servo connection, then try to move the hub at full negative camber, then move the kuckle left and right, both at zero camber and negative camber, with shocks at full stroke. lastly read this article from rc car action november 91, written by frank masi, concentrate on the chapter bump and grind.
