That would definately need to be considered!!!
Given that the 4wd system only diverts torque to the front if needed, if the RR has front and rear rollers which are effectively independant then a much larger percentage of torque would go to the front. I don't know if this could cause temperature issues in the viscous coupling, but I bet somebody else will....

With a 993 the 4 wheel drive can be decoupled in 15 min to allow them to be tuned on a 2wd RR, not sure if its as easy on a 996, all those water pipes may get in the way :grin:
