lug nut torque ?
I took the stock chromed wheels off my ZR1 to clean the wheel wells. Now that it's done and time to remount the wheels I can't remember the torque that should be used to tighten the lug nuts. Will one of you help this senile old guy out...PLEASE? TIA

You are both correct IAW Helms manual :
140 N m or 100 lb ft standard wheel
110 N m or 80 lb ft compact spare
However, I don't think he cares about the compact spare.

Going to 100 makes them a beyotch to get off sometimes.

100# is manufacturers recommendation. Although it is true that it can be a biotch to remove by hand if you get a flat, IMHO I'd rather have it harder to get off than easier to come off by itself 
And yes, 80# is the man. reco. for the spare, but then again a spare is a tire that's only reco. to drive around 55mph.

If you use use grease or antiseize you would have to increase the torque beyond the 100 ft-lbs.
The 100 ft-lbs is for dry threads. It gives the correct friction to prevent the dry lug nuts from backing off

I use 100 ft. lbs when I'm at the garage and I have the wrench handy. Otherwise you can get a feel for "tight enough" if you do it enough time. Sure the torque wrench is always better, but a calibrated elbow doesn't hurt.
You can do like my friend does and torque them to "two inch pounds," when the vehicle rolls two inches, you're done.
