Ok I know these things just came out but I was looking at a magazine last week on the Boss and saw pics of it's Torsen. The internal gearing looked very beefy (especially when compared to the Fd's unit). Too me it would seem like a nice upgrade for the Fd for those that track their cars on a regular basis (if made to fit). I know we have the Kaaz but aren't those mostly engineered for straight line performance?

I'm gonna try to find some pics.

 

Most 1.5 way clutch types are great for track cars, you may be thinking of the real harsh 2-ways more suited for drift or drag. Not sure the mustang LSD would perform any better or be worth the trouble over installing something like a carbonetic 1.5 way.
