Never got around to posting, because some one was complaining about this thread being too much talk and not enough flex pics. Well if its talk about how to make your rig have extreme flex, then it belongs here I think.....  but this is my double shackle setup, done a little differently than anything I have seen......(thanks fordh8r for sharing your ideas)
It is yet to cause a handling problem of any kind, but the 63's flexed so well the tire took a bite out of my wheel well and broke a bunch of plastic....Bump stops are a must for the 63's......
