I dunno. Don't they get scratched/chipped from wrench use? Will be nice to have to hang around Tire Rack (or Porsche service!?), to loosen them yourself; I can't trust the guys there to do it right.
A 500Nm torque wrench weighs about 13 kgs (not including special socket); kinda negates any weight savings, right?
The advantage is what? They look cool? Faster Roadside Service for non-existant spare?
OTOH, Niiiiiice, besides..., anything which gets me closer to a CGT I'll take.
