Deceiving as it may seem, you do in fact need more than two nuts to go fast.

lol, leave it to Damon for the commentary.

Need to check Rishie's Enkei GB thread to see if the owner is there.

Speechless.

I can't figure out how that couyld happen, even if you forgot to torque them. The studs seemed to be intact.

Not on the rear drivers - all five looked sheered off at the hub?

Maybe he had them on loosely (finger tight) and the vibration stripped all the lug nut threads.

Really odd.

That's the story I heard.

Pure conjecture: I imagine since the wheels were aftermarket that the hubcentric rings "stuck" the wheels on tight enough that they were fine until loaded up. The lugs were only on a few turns so once the wheels began to wobble they ripped the lugnuts off by stripping the threads from the studs.

I still can't believe all 4 seperated at once. That's impressive!

As I have been told from fellow auto-x'ers at the event, the driver had recently purchased some wheels, and the lug nuts he had did not fit.

He went to buy a new set but was given some with the wrong thread pitch. They seemed to torque on fine but stripped off some material.

The rest is obvious.

Having bought RPF1s & nuts from Rishie's GB, I'm VERY interested in - and worried about - this.

That just hurts to watch. The damage must be pretty extensive too.

He supposedly got the lugs from a different place than where the rims came from (hence the problem, probably from Autozone or Pepboys). Personally, I have a set of rims from Rishie and his lugs. I've run them on the track without issues.

How the hell could you get wrong-thread-pitch lug nuts, and not notice that it doesn't feel right going on? Did he blow 'em on with an impact gun or something?

Yeah, I'm not really that worried. Peter's post ^ looks about right. You'd need something like aluminum nuts to make that mistake. A batch of defective alloy or incorrect heat treating might be a different story, but I would notice the wrong thread during installation.

That's incredible! I wonder if there is any liability action that might occur.

If the nuts stripped the threads..........why are all 5 studs broken flush off the left rear hub?

Poor bastard

I found this on another rotary forum. Seems that someone sold this guy lug nuts with an incorrect thread. They torqued down ok, but failed when cornering loads were applied.

This brings up the obvious question. If we purchased new wheels, how would we know that we have the right threads?

Purchase everything through Rishie at AutoRND. You'll always have the correct equipment.

The other thing is not to ask a shop what lug nuts fit your car. Go to the shop knowing what fits your car.

Maybe the thread title should read "Before launch, check the SIZE of your nuts".

Talking Hilarious!!!

I can't stop watching this. That's the funniest ******* thing I've seen in quite a while. By a long shot. I particularly like the driver's use of the parking brake.

And who is the idiot counting lugs? The driver?

Thanks for sharing Damon.
