The answer in the STi Service Manual. For aluminum wheels it says "see steel wheels". Steel wheels says: 65.7 ft-lbs of torque.

Note to Subaru: don't ask me to use "specified torque" without specifying the torque. It's not listed anywhere in the owner's manual!

Yeah, that's the previously mentioned "55-72ft-lbs" spec for the spare, not for the real wheels.

Don't even try to defend Subaru on this point! They've left this important info out of several versions of the owners manual. :(

I'd rather go with what the Service Manual says. FHI never lies, but dealer techs can get confused. 75-82 isn't even within the range that the donut tire is supposed to use.

Yes, aluminum wheels. The service manual says the specs are the same for both aluminum and steel wheels. This is the same spec, by the way, that the GC8 had.

I'm no mechanic, but I've read that the reason you don't want to overtorque the lug nuts is that it can warp the rotors. Dunno if that's true, but it is true that if you put tin foil in your wheels, you can jam police radar! :lol:
