Nice! yeah I would love to go 4link however I live in Ontario, Canada. and they just keep getting more and more strict... Now we cannot have any lift installed unless it meets or exceeds OEM spec and is mass produced... Which means no custom lift kits.
There is a guy on facebook:
https://www.facebook.com/ringdingdingracing/That has 1.5" lift springs in the rear and stock LJ50 rear springs up front and running 33's, you can see the trimming was kept to a minimum and it looks great.. That is the stance I believe I am going for, however if ontario wasn't so strict I would definitely do a 4link system with airbags or airshocks to get the most out of the flex.
Then I could air them up/down depending on the terrain since I do some mud bogs(be good to air up on those however likely will reduce doing bogs eventually and focus on trail) as well as sand dune riding(lower the better here) and eventually wouldn't mind some light rock crawling.
