FYI have you considered long arms? When you price adjustable uppers ($180 ish), lowers($200ish), and drop brackets($350ish) you are around what it would cost for long arms. Even more expensive than some. Also if you paln on going bigger then why not do it now? You can get a long arm set up from $400-$900, just depends on what you like.
You can do just adjustable arms but your ride quality will suck with the geometry wrong. I was sitting at about the same lift with adjustable uppers and lowers and it was still a harsh ride. I would really consider long arms for the moeny and time it takes to do the other version. That's my two pennies.
