When I was shopping for wheels for my IS-F I used the ISx50 as a reference point...that was a mistake. Since the stock ride height of the ISx50 is significantly heigher than the stock IS-F height and they have essentially the same camber settings at the stock heights - when dropped, the ISx50 will have much more negative camber than and IS-F at the same ride height. Also JoeZ had mentioned that the rear axles on the IS-F are 1/4" longer. Therefore, the ISx50s can get away with a more agressive wheel fitament than an IS-F.
For my first set of aftermarket wheels on my IS-F, I went with a 19x10.5" wheel with +22 offset and 265/30/19 tire in the rear. The tread of tire rubbed against the fender lip - the side wall was completely outside of the car. I brought the car to a couple of body shops to have the fenders rolled or even pulled - in the end, the conclusion was that I'd need to pull the rear quarters out at least 1" for the wheel and tire to clear the rear quarter. I thought about just going widebody but in the end didn't think it was worthwhile to do paintwork on a car whose paint was still virgin...so I just ended up getting a new set of rear wheels (cost more than the body shop estimate for the body work, haha).
For the fronts, the IS-F should be able to run something more aggressive than an ISx50 can run since the fenders of the IS-F are wider.
For reference, here is a 19x10.5 +22mm offset wheel with 265/30/19 tire on the back of an IS-F:
I don't know why I even attempted to drive with those on, haha.

It all makes sense, thanks everyone! 
I had a Z as well.. I had 19x9.5 +12 and 19x10.5 +12 with semi-meaty 245/275 set up.
Im actually trying to sell my Volks for a set that will fit my IS-F. People are throwing +22 offset volks at me left and right...
Gah! Looking at this picture makes me want to keep the wheels! I will probably get mag blue volks in the correct is-f offset. Its my favorite all-time wheel.

LOL I'm super calm, what do I care if someone wants to "ghetto-rize" their car, not my money 
be my guest!
The IS-F/M3/AMG cars are not s2000, 350z, G35's or other cars that are meant for crazy offsets. I was following an older Q45 the other day with rubber bands stretched on rims that were probably running 20 degrees negative camber ~ so stupid. Looked like he was going to crash any minute, those are not only dumb looking but an accident waiting to happen.

I wont be insanely hellaflush and cambered, but I like to push it a little.
Its just a daily driver. My rule of thumb is.. find a set up I like, subtract 5-10mm from the offset they use.
