I use ATE.
It is standard on Porsche. I want to believe it makes the truck stop faster (hahaha).
The ATE fluid does have a higher boiling point and additional moisture inhibitors than other standard brake fluid (even more inhibitors than Castrol LMA).
If you are flushing old fluid out, ATE has both a regular gold/brown color and a blue color brake fluid. Using alternate color fluid makes it easier to tell when you have finished flushing out the old brake fluid.
I got mine locally but here is a url from Tirerack for ATE
