Seems like you are running too much arm toe in. Typically you want arm toe out (sweep).

If you kept the same relation before, except sans- 2mm shims, then the car was set too narrow in the FF mount.

Personal suggestion, take the 2mm shim out from in between the FR mount and the bulkhead. Use a 0.5mm shim instead. In the FF add 1.0 mm of shimming more in between the arm and bulkhead (for a total of 3mm). You should not have any more binding issues and will have a much better front end geometry.
