I don't think this is correct as printed.  The torsen only shifts front to 
rear bias, locking the rear diff really doesn't affect that at all.  The 
torsen can and will transfer power whether the front or the rear diffs are 
locked.  It *will* change the character of the torsen during turning only, 
with no ill effects.  What I have observed with the 15mph lockout at 
steamboat (Dave Lawson did this mod to his T44), is that when the torsen 
sends the power to the rear, the back end wants to get out in a hurry.  
Seemed pretty tough to control consistently.  Let's not forget that the self 
unlock of the rear diff was a saftey and consumer feature cuz of the 
knucklehead behind the wheel, not because of the torsen.  All issues on the 
torsen C/ locker R were to eliminate the active driver involvement in low 
traction conditions.  You will also find that the R locker will auto 
disengage when you shut the car off too, regardless of BL/WHT wire interrupt.

I was doing research on this and if you keep your rear
diff locked after 15 mph you just might mess up the
torsen diff..  the torsen is not suppose to be unable
to transfer power... This is why audi made the rear
locks the way they did...   you might want to buy a
4000 or a 5000
