Great write up, I've been running a 1" Roger Brown bodylift for about a year now. I met Roger back in the late 90's on a Rubicon trip. Super nice guy, I ended up buying his 5.29's and True Trac from the front diff of his 4 runner. Anyway the body lift is perfect for running tires bigger than 35" with less suspension lift.
I'm running 37's with J springs:
