That will be some impressive work. Will you still be running the standard shovel or are you be thinking of a tummy tuck with lowering it that much. I accept that with the 35"'s your ramp over will be fairly good.
I am running about a 3" suspension lift and am presently struggling with some vibes around the 100/110km/h mark (I have a tummy tuck which raised the tranny by just over 1", no MML or BL). I am thinking of throwing in a 1" MML in but to do that I will really need a 1" BL unless I modify the tunnel fairly heavily. I have never been a fan of a MML and BL but am not really in a position atm financially to go with what you are doing up front and maybe outboarding the rear shocks. Will watch this with interest.
