I have every confidence that this "trick" will work as well, if not better, 
on Torsen-equipped cars since theory suggests it has the potential to reduce 
the amount of torque that is shuffled back-and-forth by increasing the 
traction differential between the front and rear wheels.  In an ideal world, 
the size of the wheel/tire combo used at any position on the car would 
reflect the potential loads to be imposed upon it.  That most street cars, be 
they RWD, FWD or AWD, have an equal-sized wheel and tire at each corner is a 
matter of practicality not enlightened design; as for race cars, the rules 
usually make this decision for the engineers, either by requiring it 
specifically or by allowing them to build engines so powerful that they need 
all the traction they can get, no matter which end of the car it's at.

In view of the above, I find it interesting to note that two well-known Audi 
tuners, SMS and MTM, have occasionally run smaller rear wheer wheels/tires 
(larger front wheels/tires?) on the hi-peformance Coupes they built for 
racing and street use and in both instances, the center diff was a Torsen...
