Just my personal opinion, but wheel spacers and adapters frighten me..if you go this route just know the risks and make sure they are installed correctly - thread locker and torqued down! Wheel adapters longer than 1.5" put a lot of stress on your wheel bearings. I was in the same boat your were. Ran 2 inch adapters on stock wheels with a 6 inch lift for about 6 months. I noticed some odd tire screeching when I would hit bumps, tight corners, or at the bottom of a hill when the suspension would have a lot of load on them (G forces baby). As soon as I went to a new wheel with more negative offset/backspacing that went away.
