Lots and lots of race teams, and the guys over at Gbox use the Delvac 75W90, which is what I have in my 996 box at the moment (which also has a Guard LSD in it) and I'm plenty happy with it. I've run the Delvac stuff for years in multiple Porsche boxes. If you go this route, you have to buy in the gallon, NOT the quart (like you find at the local Autozone), as apparently they are grossly different fluids.

Supposedly, the "new" Audi manual trans fluid (what comes in, say, a new S5) is the cat's meow, but it's something like $60/quart from your dealer!!!
