I test fitted my update set when I still had it and it was fine - but it does need the 4 plastic rivets to hold it secure.
I have noticed however that each splitter seem to be moulded to a particular bumper (I have two bumpers so makes it easier to notice things like these) and swaping one splitter to the other bumper does create fitment issues (i.e doesn't perfectly cover the cut-out in the bumper)
