That's an inexpensive way to fit 35's. That's about all that I can say for that lift that's positive.
I believe that you would be disappointed in that kit if you want to take your Jeep off road. When compared with other lift kits for the JK that allow 35's, that kit will not provide any increase is suspension performance at all. You may also have issues with "flighty" steering, bump steer, and off-center axles.
To be honest with you, I'd recommend wheeling your rig exactly as it is (or with a stock size set of MT tires) for a while. This will allow you to save up some money, learn what your rig is already capable of, and figure out what you want your rig to be able to do. It will allow you to actually talk face to face with the people giving you advice, and quaqlify what they're saying based on what they've done to their rigs, and what their rigs can actually do on the trail. Yes, doing that takes more time that soliciting advice from all of us super-duper web wheelers, but you'll get better results that way.
I could tell what I bought for my JK, and babble for three pages about why it's the absolute best way to put your JK on 35's...but that wouldn't do you much good if you don't have the same priorities for your Jeep as I do for mine. Come to some meetings, come to some open runs,
come to the Xmas toy run, and just walk up to someone that has a JK that you like - you'll be shocked at how much you learn. You'll also be shocked at how hard it is to get a Jeep person to SHUT UP once you get them going about their Jeep.
