Offset of 52 WILL NOT FIT. For an 18X11 to fit the rear of the Boxster the wheel will be sticking out past the fender. My guess is an 18X11 needs an offset somewhere between 38mm-43mm.

That's what GAMBALLA does. Wide wheels and tires in the rear that hang out past the fenders. Looks like your right, 18x11 may be to wide. But Gamballa uses 18x10.5 in the rear.

If I were you I would do 18x10 and get your offset around ET45 (either by getting the correct wheel or using spacers if need be).
At the end of the day, there is very little to be gained by going beyond 10". I'm actually considering doing 9 or 9 1/2 on my next set of wheels. I run a 265/35 on my 18x10, but alot of guys run Turbo size rears at 285/30. Even if running the 285/30 you're not going to put any appreciable amount more rubber on the road by going to a 10 1/2" or even an 11" wide wheel.
I can assure you that car below has A LOT of rubbing going on.
Also a 275/30 on a 11" wheel will look stupid in my opinion. The tire will stretch out too much. You will have a big lip on the outside and inside of the wheel that has no rubber to cover it.
