I would call RCX and ask them what they suggest for BS and Offset with that kit.

Don't go wider than 8.5" - 9" and keep the offset around +18 or so. If you go with a 12.50, they will still probably rub.

Point taken, I don't have any experience with the NNBS, I just figured that since 305 fit on mine without issue the same would be true for the newer trucks.

I'm not exactly sure why, but I've been told that strut spacers for these trucks cause the front tires to suck in as well. That could be part of the issue.
