Those 'special' lsd gear oils were made because they reduce noise of the friction plates (in slow corners or in the parking lot), which is very liked by the typical Porsche owner who wants a comfortable a relatively quiet car.
I just want performance
Thanks for the intel, I'll pass it along to one of my friends who doesn't really care about noise (1983 RUF SC) and I'm glad I was wrong but I'd rather be wrong than hear about a broken lsd...

Have fun on the track...

Seb
