It isn't my reasoning, it's Porsche's. But, to answer your question, no. As I understand it... not only is the torque a minor concern, but the vibration and intense heat cycles associated with the caliper would weaken or make brittle the bolts over time. Not so (as much) with the lug nuts. Vibration yes. But they're far enough away from the heat source so as not to undergo the extreme heat cycling the caliper bolts do. Hey.. I don't make the rules. I just (sometimes) try to follow them!!! And the only reason this came up is someone asked a question. sheeeeeeesh.
