I'm going to be painting the calipers and wonder if i need to torque down the lug nuts, or just tighten them real good with a tire iron.

The torque wrench is your friend. It will help prevent warped rotors, caused in part by wheels that are unevenly/improperly torqued.

Buy as good of one as you can afford. It will last a long time. (and don't forget to unwind it to "zero" when you're done with it)

Santa left a Delco ARM 602-3 and a ARM 602-4 torque adapter. Neat packages!.

Yes, you will save yourself some busted stuff, and check them after a couple of heat cycles. lugnuts 100ft-lbs

I always use a torque wrench on my lugs. 100 ft lbs each.

Definitely get one. I use a torque wrench on any bolt that has a prescribed torque number.

By far my favorite tool.. well, besides an impact wrench

Baldfart

That looks like a nice wrench for the money!

Also the post about "buy the best torque wrench you can afford" A very worth while tip, this is one of those you get what you pay for! things

This seems to be the way to go nowadays. Back when men were men and wheels were steel, you would just crank them down with a lug wrench.

You really do need to use a torque wrench for the final snug of wheel lugs. Not just on the Corvette.

Have NEVER used a torque wrench and have never had wheel fall off.

If you use a LARGE X spinner you can torque the lug nuts by feel.
Just tighten every other lugnut and bring them all up to tight but not stud breaking.

Can see using a torque wrench on head bolts etc, but not on wheel lugnuts.

Toque,

I may be too tired, but, I don't see any wheel lug torque specs in there? It's got everything else...

Thanks Bill,
I was willing to trust the above where they said go to 100ft lbs, but I found it interesting that it wasn't listed in the chart.
