Well, I've got my 3Racing in my M05 and a very smooth TA03 in the M04. I think the Xevo is going to get either last years ball diff, which was wonderfully notchy or a shimmed stock diff. I'm also considering a TA03 with those 3mm Delrin plugs that replace the balls, effectively making it a slipper spool. Tough call. Better decide though. Changing the diff in a Xevo is a bear.
