Where can I find whether 1999 XK8 has already factory mounted eccentric camber bolts? I tried to turn mine using a bubble level as a measure, but could not see a difference despite that by visual it looked that the arm was slightly moving.

 

The one eccentric bolt is for toe in. Camber is set by shims installed in the differential.

 

Please specify front or rear suspension.

If you are referring to the front lower control arm adjusting bolt it is part # JZB100085.
It is not much of an adjustment but it is a little.

Pull it out and inspect it!!!!!!
