It is also interesting to note that Porsche's "max effort" cars, the GT2, GT3, and Turbos, all run 160F stats from the factory.

I'm metric when it comes to oil and coolant temp. My car runs at 88 or 89C steady state. That's totally fine.
What I don't like is how hot it can get when stressed or in traffic.
Moreover, the thing the low temp stat is advertised as being preventative for is bore scoring on some of the larger M97 engines, which is supposedly a problem related to very high temps and hot spots.
But I am at a loss as to how it does this since at higher temps, there's no difference between the two stats.
GT2/GT3/Turbo all have very different engines (well, did until the Mezger was dropped fairly reently). There are lots of things they have that may or may not be a good idea for the M96/7 engines.
