For specifics on the LSD better to contact Tom, but I think not much customization was needed to the quaife unit to make it to fit the stype.
It works pretty well with traction/control / DSC, as that one only comes into action once a wheel is actually spinning, and that only starts after the ATB (Automatic Torque Bias) type diffs do there work first.

The magazine guys had an in-house project Integra of some sort, and decided to add a Wavetrac LSD. On Day 1, they dynoed and ran the car several times in the 1/8 mile with the stock open differential. On Day 2, they did the same with the new LSD installed.
The car improved its average 60' time by .332 seconds, from 2.533 to 2.201 seconds. Its average 1/8 mile time improved by .349 seconds, from 10.15 to 9.801 seconds. I used an ET calculator (of unknown accuracy) to get an idea of what this would translate to in the 1/4 mile, and it shows a 1/4 mile improvement from 15.83 to 15.29 seconds. In order to try to assess the accuracy of this calculator, I grabbed one of my timeslips from last year and entered the 1/8 mile times into the calculator; after entering my 1/8 mile time, the calculator estimated my 1/4 mile to be .145 seconds slower than it actually was, so consider that for whatever it is worth.
A 13-second car is not going to see the same gains that an Integra would. However, it is apparent that there is at least some quantifiable improvement upon installation of an LSD. Considering these results, and how much torque we are producing, and how easy it is at the moment to launch with only one tire spinning, I can't help but think that the exaggeration is warranted...at least to some degree.
