I doubt you're going to see much (any) settling. No harm in putting a few miles/days on it though.
The ride was surprisingly different after just dropping that 1/2-3/4". When I first lifted the 100 (Ironman TBs, springs, shocks), my first thought was "Well &$#*. No more comfortably Land Cruiser. I've got a damn truck now". Dropping the nose down that little bit returned it to that awesome ride we love about these things.
This is the before and after - day 1 with the lift vs "after" dialing it down. The bumper and winch were added after dialing it down, and yielded less than a 1/4" drop.
