here has been my progression.
Started with stock spring over lift (4-5" can't remember exaclty been so long), 31" tires ( some fit 32" with some rubbing). little better flex than stock. worked ok.
Went to a Ruf (rear springs up front) setup w/31" tires. Flex improved alot. Better ride. little more lift (approx 6"), I also ran 1" wheel spacers to widen the track width to keep it a little more stable. Could easily fit 32" tires. maybe 33's with moving axle forward 1". This setup worked out well the only reason I change is because I got a set of YJ springs.
Now I am running the TT YJ kit on toy axles with 33" tires. Great setup. It is more pricey, and you need a trac bar, but I am going over stuff. With the wider stance and no added lift (other than the bigger tire) now It feels more stable than my previous setup.
