Just got done with the install. Super easy. But I don't see how you could do this without removing the two 17mm bolts that hold the torsion bar on the front lower a arm. Easy once everything was loose. Took a 5lb hammer to break the splines from the two attachments.
One weird thing though: I took my time and cleaned all threads super well and greased everything, and now I do not have to lift the VX off the ground to turn torsion bolt and adjust height. Granted it was not super easy but I did not need a breaker bar (my socket is pretty hearty though). I was just turning and adjusting with the VX on the ground and it was raising and lower the VX accordingly down to the 1/4" for every half turn. Once you take everything off and see how it works you will never forget that tighten the bolt will force the lower a arm down. Can't wait to road test.
From ground to top of wheel well I am now:
40" REAR
39-1/4" FRONT
