I've had my 2015 PP for about a week now, with the Torsen. Mine makes the clunk (from the trunk area) the loudest from neutral to first, however, if I hold the clutch in and wait for a full second before putting it in gear, it doesn't do it. Same for going from first to second, no clunk if i leave the clutch in longer before going to second. It makes me not even want to use first, and just start in second. With the 3.73's, 1st is almost pointless anyways.
