I bought this setup for my j and havent got much use out of them cause the car is stored or im working on it. so I was curious how this setup has treated other people and are they durable i have mine pretty low like there are only 10 more threads to go down to the bottom is that unsafe or can i put them all the way down? I havent got alighnment yet! i also got the camber bolts for the front are these needed for the alighnment right?
