Do you want it lifted to clear 30" tires - or do you want it lifted to look cool in the mall parking lot, make the handling worse, have less sidehill capability, and generally make it fall further behind the leaders on the trail?
Lift is to clear tires - generally because we don't want to cut out the fenderwells like we should, or are running rims with so little offset the treads rip off the flares.
I'm not so much for lift if you are running 30" tires or less, and haven't done anything to the axles. It's just trail bling at that point. Over 30", you need better axles and a decently engineered set of springs. ACOGS, long arms, new springs, whatever - but just 2" isn't really justified most of the time. It's just a bandaid to clear rims that are all wrong.
