man come-on!!!!!!!!!

OUCH!!

righty tighty, lefty loosey

AHAHAHA!!! Oh man. I know I shouldn't laugh because I'll probably end up doing something similar, but oh man, I can only imagine what it would feel like to be that guy. He must have done thousands in damage to that RX-7. Talk about a stupid tax . . .

That's one of my friends that I autocross with in the Dixie region. Really stand-up guy, the last person to work on his car put incorrectly threaded lug bolts on his car, and the owner didn't check. Car has minor body damage, and the car was flatbedded home (from Valdosta, GA, to Tallahassee, FL). All of the details are still coming out about this, so don't want to post any more as I'm not 100% sure of any of it.

wow :eek:

if its just minor body damage at the end of the day then I think he got lucky and hopefully learned a lesson about the mechanic and checking that your lugs are torqued.

:embarrasm I thought the video was staged at first until I realized no one was laughing. Sucks that it happened, glad that it was minimal damage.

That body damage is hardly minor. From the looks of it it's several thousand dollars worth of damage in addition to any possible damage to the wheels.

That situation is exactly why I remove the wheels from the car before having new tires put on them. Then I put them back on myself and mark each one as torqued before moving on. I've seen too many instances of absolutely bollocksed cars and wheels from having lug nuts incorrectly tightened.

If the bolts were incorrectly threaded, torquing them would have highlighted it instantly.

I constantly observe DE drivers never checking their wheels......


so much so I almost feel silly checking mine!........but K1's have a bit of a history...:eek:

wow, i'm neurotic about checking my bolts, but all four wheels damn

WOW!! :eek:

After having a wheel (Kosei K1) get loose on me at WGI, I dumped the wheel bolts, went to studs and check all lug nuts on every wheel after every run. Its so routine now, I dont think about it and on a few occasions I have to double check myself, by checking all nuts a second time.

Last week at LRP, at a CCA club race, we checked and rechecked the car upside down and sideways, brought the car to staging before the Tuesday morning sprint (I was wrenching for my co-driver that race), and brought the torque wrench with me to staging just in case. Sure enough, 5 out of the 10 lug nuts (TC Klein stud kit) on the two right wheels weren't even finger tight...two full turns looser than that! Very, very scary. Yes, we run Kosei's.

My lug nuts loosened up on me this week as well post break job. They were torqued on properly but a week later they were definitely loose. I'm happy I didn't have to pay the price.

Youre married now..still checking your nuts?????????????


..anyhew.....can we all say OCD?........I think all of us have it a wee bit.
:buttrock

I just want to know how you get ALL 4 WHEELS to come off at the same time. Talk about bad luck! And really, how hard is it to notice when a bolt/nut don't thread together correctly?!?! If that truly was the case, that shop has no business being in the car business.

Yeah - it's almost unbelievable. Wouldn't he have felt the wobbling as he was gonig up to the start line?

arrrgh, link no worky!

Now that I've heard that he did torque them down before the run and that the shop he went too screwed up by putting the wrong size nuts on, I can only imagine the small claims battle this is probably going to become. If the shop truly did put the wrong size nut on, I hope they compensate this guy for every dime of expense he incurred.

How about mental distress? lol He's going to be internet forum star now :)

On a serious note though, for the track/race guys who have their wheels/hubs get very hot, don't forget to NEVER re-torque the studs/bolts while they are hot. Wait for them to cool down if possible. Obviously during endurance racing when they do quick pit stops, thats not an option, but they are also not necessarily using the same hardware.

So at a DE event on a hot day at thunderhill my front right studs starting coming loose. Are you saying, that after this occurs I should just sit out the rest of the session? I just jacked the car up and tightened everything down again...hot and all.

I know my cars not getting anywhere near the temps that a race car is getting at though.

I was just about to say that.

Also guys, watch the "torque creep". Not to be confused with a trenchcoat-wearing lurker carrying a lug wrench in his hand, torque creep is when the user moves the torque wrench a little too hard/fast to get the "click", and ends up twisting the bolt/nut ever so slightly. It can add up to overtorqued wheels over the course of a day or weekend.

Well, You don't necassarily need to sit out and wait for it to cool, but think about it. Your brakes get hot, the wheel bearing/hub gets hot, it dissipates into your wheel and to your lugs. Now everything is expanding/contracting while heating up and cooling...and now you go and retighten it while stuff is hot. When parts go to expand/contract when you heat up and cool again, you run into issues.

If you are having lug nuts come loose, you should look into why, as they really should not come very loose after going on track.

Are you suing lug bolts or Studs/nuts?

Tighten BEFORE you go out for a session, and as mentioned don't do the quick torqueing just to hear the click, doing more bad than good.

My situation was based on a heat matter I think. I'm using Turner studs and they started backing out, a couple others were having similar issues. And ya, I torque my bolts every session in fear of something like the above happening to me.

What nuts/wheels are you using?

You have to be careful not to damage the nuts/studs from over tightening, b/c this can also lead to the nuts not creating a tight fit to the wheel and becoming loose.

I'm using typical k1's on 255 Falken Azeni's. I ussually tighten 80-85lb's.

Wow, lots of comments about how the K1s are "losing" torque. Sounds like the wheels are compressing or the cone mating surface under the nut is distorting enough to lose torque. Glad I bought SSR's instead. I'd never put up with having to retorque after each heat cycle.

The problem is usually powder coat built up in that area. First thing to do when using new Koseis is to get that crap out of the mating surfaces.

Look carefully from 1:08 - 1:12 in the video, did he pull the parking brake...

I doubt he was going anywhere. :lol

Define quick torqueing for me.

I hand tighten and finish with the torque wrench. Every other session I check again with the torque wrench, occasionally one of the lug nuts will have loosened a little. But on the other lug nuts this might lead to over torqueing? Are you suggesting breaking down all the lug nuts and starting over before each session?

Yeah. From what I've heard, 5 minutes with a dremel tool will solve that problem permanently.

I noticed that too, he definitely pulled the ebrake, not that is was going anywhere :D
