This one is right up there with the A/c in a Hyundai.
With the official kit, no problem as the surround will have been designed to put the strength back that you are taking out. If you do this yourself you will want an absolutely level floor and NOT to climb over the car or open the doors while it is sitting with a great big piece of metal missing from the roof.. and you'll have to replace the headliner and so on.
with an aftermarket one...I wouldnt even try it on a modern lightweight unitbody although I am sure that a professional shop would do a good job... defined as no rattle, no leaks and no wind roar.
