Just to clarify that, the engineer told me that you could change the 
torque _bias_ which as I understand it is the ability of the diff to 
transfer torque to the loaded wheel.  As it is, it is a fairly light duty 
torque bias to preserve smoothness in everyday driving in a luxury car.  
If you increase the friction in the gears though, you can get it to act 
more like a racing differential, yet retain a fair amount of smoothness 
that most racing diffs don't have.

It was _my_ opinion that if you adjusted the friction unequally (front vs
rear), you could achieve a static torque bias to the rear so that more
torque goes to the rear under all conditions.  That might stop the
instability of the centre torsen a little.  I'd sure like to try it.
