Axle nut torque

[Filastein]

Torque is, by and large, a value of the size of the fitting. Big thread diameter = big nut = big torque.

That and Porsche's desire to limit part count. I believe the front hub is the same part as the rear, just with different hardware behind it.

Exactly.

And, when you tighten something to a torque value, you are stretching or distorting the component, creating permanent tension. Takes big power to do this to a big part.
