Default Torque specs for lug nuts

Can't seem to find the exact specs in the manual. Anyone have recommended specs for lug nuts for 96 camaro with stock wheels? Thanks

ya know I've never even specified an amount of torque on any car i've put a wheel on - just put it on 'tight' without killing it. Haven't had a wheel fall off or come loose yet.

I normally use a breaker bar, and go by the ehhhhhhhh method!
Once you've installed and removed wheels enough times, you know what is tight and what is too tight without using a torque wrench.

Just don't "spot torque" the lug nuts. spot torquing is torquing the nuts so tight you see spots.

When I was a tech for GM we would set the steel wheels at 75 ft lbs and the aluminum ones at 85 ft lbs

93 factory book calls for 100 ft lbs. i do mine at 90 and the tire shop i got the wheels from recomended 90. use the star pattern when tightening and use multiple passes snug- 30- 60- 90. last thing you want is an uneven torque job. that can mess up the rotor.

yeah anywhere from 90-95 is good. I learned that the hard way.. didn't have a torque wrench so just did it realllly tight. next time. had to use wd40 to get them off haha

Ancient thread I know, but here's the definitive answer from GM eSI, since I was searching for the same information:

"Tighten the nuts in a cross sequence to 140 N·m (100 lb ft).
Tighten the wheel nut caps to 6 N·m (53 lb in)."

I have not put a tire on a car without a torque wrench since I was 17. 100 Ft lbs unless it one of those large franged 80's sytle aluminum mag wheels, then I do 80 ft lbs.

GM says most rotor warpage is caused but uneven torque on wheel. I have never warped a set of rotors on one of my cars. My wife tends to ride the brake, even tho her wheels are on right she warps them in about 2 years. So GM is full of it
