Are you talking about the whole axle housing moving? If so I'm sure it is a little bit, but the tires are actually closer to the frame than that rim is to the shock mount and there is just a touch of evidence of the tire rubbing the frame. Plus, that shock mount is attached to the axle housing so if it moves, the shock mount is going to move with it.
When I took the spacers out and put the grinder to the shock mounts, I thought I had plenty of clearance on both sides. Once I put the wheels back on I discovered that my index finger would fit between the rim and shock mount on the passenger side and only my pinkie finger would fit between the rim and the shock mount on the driver side. I figured it would still be enough though which was a mistake. 30-60 seconds with a grinder will fix this so it really isn't a big issue...but I thought it was interesting to show just how much the rim is flexing under pressure.
Also, there was NO marks on the rim after the first three runs, it wasn't until after the 4th run the rubbing actually burnt through the shine seal coating on the rim...so even though it sounded HORRIBLE, it must have just been touching, not really grinding into the mount.
