So I have an 05 crew cab ZQ8 and Im looking to lowering it 2/2. I bought the Belltech kit with 2" ball joints and the 2" blocks, couldn't really pass it up for $267 shipped. My questions are. Will there be any problem getting a good alignment or do I need to buy like a camber kit or anything else? At what point do I need to do a notch in the back? Also at what point do I need to worry about the getting the pinion angle shims? I've also ordered the JTR crossmember so that will be taken care of also. Thanks in advance.
