so this weekend was the last houston autox i could attend this summer and well first wheel i take off, front drivers side, third lug i loosen feels crossthreaded. After talking some people i go ahead and take it off and stud snaps.

Dont remember crossthreading it at last track day cause i try to be careful. but w/e so i didnt get to run.

just wondering how many of you have done the same thing? lots of people recommended ARP studs and some TL open ended lugs. and yes i did search and saw all the other threads, none in this section

If you crossthreaded it, you're SOL anyway.

Broken studs normally happen from over-torquing when you put them on OR putting cold nuts/wheels onto hot studs. If you've got aluminum or titanium race nuts then switch on OEM nuts that have been sitting around while you're running, well, as the nut heats up and the stud cools down, it can stretch and weaken the stud.

I always let my car cool for a bit, then hit everything down there with the 'ole water sprayer before I do anything.

I suspect the crossthreading or overtorquing would be the factor.

88,700km - lots of racing miles and lots of taking wheels on/off but no problem with broken studs.

Sometimes it may just have been a weak stud. I know Nissans (Sentras at least) have fairly weak studs and should definitely pay attention to how you torque them.

Also, even though you didn't overtorque at that event, if it was overtorqued - especially if it was severely overtorqued previously, that would've been enough to weaken the stud.

My friend torqued his wheel with an impact gun (air compressor, no torque sticks). His studs broke, but they didn't break until 3 months later. But then all 5 were like sheared off.

putting on oem nuts while racing will be doing what for me? i'm almost positive i didnt crossthread it but thats only reason i thought it wouldnt come off. i torque to 90 with a torque wrench everytime

i was using gorrilla locking nuts i got off ebay, guess that could be it too

What the fuck kind of statement is that? Don't try to be a dick to people who are helping you, especially when you're too stupid to read. What I wrote didn't say SHIT about racing on OEM lug nuts. If you READ it, it says that you TAKE OFF aftermarket nuts, then PUT ON OEM ones. *MOST* people I know race on aftermarket wheels & nuts then swap on their street tires which are mounted to OEM wheels which use OEM nuts.

Oh, there's your problem. You're an idiot. You're overtorquing everytime. Spec is 80ft/lbs. Why didn't you know that?

woh man, thats why i asked as your statement was misleading. geez not trying to be an ass.

90 is what i had been told by other racers....my mistake.

and yes i use aftermarket wheels/lugs but keep the lugs on both sets of wheels...street and track which are both aftermarket

oh shit, my CRSX anger issues is rubbing off on dan..

But yea, I used to torque 90ft-lbs and forget about them.

But I now just run the 80ft-lbs torque spec and I just check them more often.

I torque to 82lb then re-check after one session if at the track or one heat if at an autox. I cross-threaded one of my Work aluminum lugs once coz I was lazy and used an impact gun without first trying to thread it in a little.
