Been potching about with it lately, welded up the diff to make it easier to use for drifting. First attempt wasn't all too well and it went bang. Second attempt is holding out well!
Also been trying to fix my axle tramp issues. I swapped the front torque tube mounting bracket bushes for polybushes and trial fitted some extra rubber in the poorly designed rubber bush which holds the end of the torque tube as you can see where its been smashing against the top of it.
Bushes were a pain to get out, so use my special tool
and new bush in:
