zenki makes aluminum 7075 t-6 alum lug nuts, quality looks real good, they torque to 70 lbs ,wondering if anyone has used them, and had any issues :wink:

Mark up

what's the torque spec for our lugs? my lowly se-r was 80ftlbs.

 

[Ken Reich]

the book says 55 to 72 ft lbs, :wink:

 

[CloNeGTS]

Wow, that's quite the range!

 

[RDiamond]

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!

 

[sakura-iro]

actually it is, but it's hard to find. i spent about 10 minutes going through the owners book before i found it. iirc it's with the spare tire information.

 

[RDiamond]

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.

the techs at the dealership ,who took the pdi school said 75 to 82 ft lbs, i guess we have to go with that :wink:

forum *group* suggestion: STi Mods

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.

tape

are we not talking about the aluminum wheels ??

 

[RDiamond]

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:

the story goes if you had peices of tin foil rolling around in your hub caps,it beat radar, :roll: :roll: :roll:
