Torquing down teh lug nuts on a 73' Z.

[New-to-240z]

OK, don't laugh please don't laugh. I have done searching and come up with a few different numbers.

TORQUE VALUE CHART

7/16" dia. 50 to 60 lb-ft

12mm dia. 70 to 80 lb-ft

1/2" dia. 80 to 90 lb-ft

5/8" dia. 110 to 125 lb-ft

But, i did tons of searching on google, and came up with no specs for our studs. I did come up with 12mm but it doesn't seem like 70-80 lb-ft is tight enough? Someone please help me out with this , as i haven't had the chance to purchase a haynes or chilton manual yet for her. I have them at 90 right now. Let me know if i should ease off on her.

65 ft-lbs is what I use street and track

new to Z , What are you torquing down? The torque values will vary from year to year on many things. Being specific is a good idea . Especially since you are going to be dealing with aluminum is some cases. Gary
