I can maybe see why you may use these new shafts on the front to stop the "Chatter" vibrations at full lock. Thou using the WO series of shafts i havnt notice any issues from full lock chatter at all.

One other thing, ive doubled up on the kit upper decks (glued together) and havnt had anything bad come out of it.
flogged out my Alloy diff out drives after first meeting (the Trf417 ones)
Expensive exercise! Lol.
