Wheel Bolt Torque
I have an 01 C2 Coupe. The owners manual says that the tightening torque of wheel bolts is 130 Nm. I converted that to about 96 ft-lbs which seemed high. Can someone tell me what the correct wheel bolt torque is in ft-lbs? thanks.

Three Wheelin'
I set my wrench to 90 lbs since I usually push a little past the click and I don't want to overtighten them. <img src="graemlins/c.gif" border="0" alt="[ouch]" />

Good advice on tightening. Do you use any coating if you're using wheel bolts rather than lug nuts? <img src="confused.gif" border="0">

I recommend a TINY bit of anti-seize on just the first couple threads if you are inserting brand new bolts to prevent stripping or galling . Never put any near the convex flange of the head of the bolt .

Too much anti-seize may mean some of it backs out onto flage as you screw the bolt in. That could lead to improper TQ and potential for the bolt backing out !

Okay... from the Technical Manual:
"* Apply a thin coating of Optimoly TA, or equivalent, aluminium paste to the thread, shank and below the head of the wheel bolts (between bolt head bearing surface and spherical cap ring).
* Do not coat the spherical cap bearing surface facing the wheel."
* If heavily contaminated, clean screws first with a lint-free cloth.

I follow the "STAR" pattern as suggested above (basically every other bolt until you return to the first one)- first tightening each nut at 80% of factory recommended NM - then I do it again at factory recommended settings. Then, after driving 100 miltes, do it again and you are all set.
