There is a formula for this that i no doubt Old Corolla will have seen , or know of the top of his head

not really but i can make something up  
say you make 300nm, in first gear (say 3.5:1) multiplies to 1050Nm applied to tailshaft.
although this torque is usually converted to forward motion, if we assume that it all goes into trying to turn the diff into a big propeller.....
say track is 1400mm, the moment arm to each side is 0.7m
1050/0.7 = 1500N (or is it divided by two? hmm must be otherwise it would spin other way.. still this is the difference in vertical force between the tyres)
so 150kg difference in traction between the tyres.
say car weighs 900kg, 50/50/50 split = 225kg on each rear tyre..
SO.. in 1st gear, 300Nm etc etc, the 'weight' on tyres is 225+-75
= 150/300....
one side has double the traction than the other....
so if your LSD does it's job, and neither wheel spins, you still have a massive difference in force being applied by each wheel and the car spins...
but as IP86 says, with IRS, this is not an issue
