ive hade my TT/shackle lift with the 33"s on for a few months now, and so far everythings been holding up pretty well. ive taken it up to the mountains, off road, on trails and in the rain and snow and its been going like champ (knock on wood). with the TT lift pushing me up 3", the ride did become altered quite a bit, but it doesnt matter what kind of lift you do, the original ride engineered by ford will always be altered. i dont mind it though, it rides more like a truck to me now. ill be due for some new ball joints next year, but i think that was going to be coming up anyway. i do have the luxury now of retiring my trac from commuter duty since i got my hands on an old civic hatchback last month. if keeping the original ride and look is most important to you and you dont go off road at all, just keep it stock, but if you are planning on getting your tires dirty, take the the plnuge but just be smart, and practical with how you do the lift, and understand that it will drive differently.
good luck with whatver you do, and post pics!
