Definitely easy to remove. A few hours labor and an alignment. A good shop can do it quick and an experienced how mechanic can in the same amount of time. A set of coils and rear control arms in an Mk4 R32 takes me around 2.5 hours to finish. Granted I have done a dozen or so Mk4 suspensions but again, once you know what you are doing it is very simple.
Sorry to thread jack.
