The dials in the 1995 car affected the suspension and brakes, not the 
differentials.   When we toured Audi Sport in the UK, the head honcho implied 
there was some great secret about the centre differential, but I now believe 
this secret is that there wasn't one!
 
The 1996 BTCC car used a carbon fibre propshaft that allowed a ridiculous 
amount of wind-up.  Perhaps as much as a whole revolution.  In racing, it isn't 
very long before the car picks a wheel up anyway, so the whole thing can 
unwind.
