TIGHTEN YOUR LUG NUTS! This past weekend was my brother's first race since he wrecked it three weeks ago. (Some of you saw the pic I posted - you know he tried to be Grave Digger and run over someone) First, his power steering belt came off during his hot laps, but that wasn't really a prob, he could drive without power steering. During the heat race, his LR was loose and started wobbling, when he finally saw us waving him in, it broke off and went off the bank into the woods at 70mph. The bolts were stripped out of the axle. We didn't have a spare, so that was it for the night. We never found the tire either, the grass was as tall as we were out there!

I agree. We check our lugnuts and our air pressures after each run. We've seen guys at our track lose their wheels, go off the track and flip their cars several times. Can't ever be too safe !

ALWAYS check them when you get to the track if nothing else, but I strongly suggest a click type torque wrench for the person that checks them. I have seen too many people that insist on slightly turning them each time to ensure they are tight. That's ok for a while then you either snap them off or have them so tight that the impact hammers awhile before getting them loose.

We tighten our lug nuts after every trip onto the track and check them before we go out for the feature. We torque to 80 ft lbs on 5/8" studs with 1" nuts. Does anyone know what the manufacturers recommend for torque?

100 ft # is the manufacture torque on 1/2" studs and that holds true for most all manufactures we use a torque stick and not had a problem

Like someone else said dont over tighten them. A new reason tho. You want the lugnut to be tight on the rim not the rotor or axle. If you tighten them too much it will seat against the rotor/axle and oblong the lug hole and thta cost you around $40.

Does anyone ever use any kind of lube on the threads? With oil or antiseize your 100 pounds only needs to aout 75-80lbs.

Don't lube them, but I do clean the threads once in a while. I would think lube would reduce the friction-torque between the threads that you need to hold the nut on the stud.
