I know this thread has slightly changed topics, but back to the original topic: limiting up travel doesn't limit droop very much, if it all from what I've seen in my short year of wheeling. I can see it being more of a limiting factor if you have short arms, but with long arms I don't think a lack of up travel would affect droop at all. Hell, I have a 4.5" short arm lift on 35's (which is fairly low in XJ land - 3" can be done on 35's though) and I can still drop the front springs off the upper spring perch. Alex completely lost a spring at River Rock in February and as discussed already, his rig is low, even though it seriously needs some spring retainers ;D
