The Calmini lift the PO put on mine had a panhard rod drop bracket. I assume that it came with the lift since I haven't seen it on anyone else's. I talked about getting Welder Guy to fab up copies but there didn't seem to be any interest. I think that would take care of the rear axle lateral shift that some people experienced with a lift (others did not). Certain other members indicated significant increase in bump steer after lifting and a panhard rod drop should help with that as well.
Just thinking outside the box.
