Engines are designed with specific running tolerances in mind. These tolerances are dependent on certain material temperatures. If the temperatures are different, clearances and pressures in the nominal running state are not the same as what the designers had in mind. This will influence things like friction, oil consumption, combustion efficiency, fuel consumption, and oil pressure.

This is why a thermostat that works for one engine, like the GT3, may not be the best answer for another.

I don't know if lowering the water operating temp in the M96 is beneficial or not, but I do know that it's not what Porsche considered optimal when designing the engine.
