Lug Bolt Torque

Could anyone tell me what the factory specification is for the lug bolt tightening torque for a 126?

It changes all the time
Don't have the specs handy, but until someone comes up with the answer, I'm guessin between 65 and 85 lbs. I actually use a low power 1/2 inch impact. I snug em up and hammer em for a couple of seconds. Haven't lost a wheel in 30 years, and I've mouted thousands of wheels. I only use a torque wrench for steering knuckles, head bolts, and valve bodies. If a professional mechanic used torque specs for everything, the jobs would never get done.

I found the correct spec, 110 newton-meters, or about 82 lb-ft.
