Complex as the center diff ??
Can you run the older style center diff in the 32 (Viscous)?? Would like to get a way from all the electronics.
Yer the weight may and may not be a limiting factor, in my searches they seam to be around 100kg heavy than the Rex/ Evo and only 100mm longer.
Travel could be the problem the Nissan GTRi had the same problems
Would love to find some body that has done one before.
Cheers
Ian
