As far as I know, the only CL failures to date have all been on non-RS cars. Can anyone verify a failure on an RS?

I've got an RS, hence my concern.

 

Not that i know of.

 

Are RS centerlocks different in any way?

 

Not that I know of. My understanding is that the parts are the same. However, the wheel size and offset is different, so it does make me pay attention to the theory posited on Geoff's thread that perhaps this has to do with loads and forces. There might be enough leverage in the non-RS design to cause higher stresses than the RS design. Can someone who knows the offsets and such chime in here?

I don't mean to derail my own thread, though. Please keep commenting about any known RS failures!

 

Did you mean to say all CL failures occurred on RS's? I have yet to see a non RS fail. All failures on here and linked videos have all been on RS's....

 

I have yet to see an RS with CL failure. Please prove me wrong. That's the point of my posting.

 

3 off the top of my head. 2 were posted here on the board. First was a known forum member and second was a failure at Nur (video link somewhere) The last was a story I heard of a RS losing a wheel in the esses of VIR.

I'm on my iPhone now, but when I get home I'll post links.

 

None. Too much Sambuca.

 

the forum member was a non RS, the one in the video at the N'ring was non Rs too...it had fake 4.0 stripes down the center

 

Nick, they are proving you wrong

 

997.2 Turbo S, GTS, GT3 and GT3RS all have the same Center Lock system.

 

Looked back and I was mistaken.

****, I feel like I just got knocked out by Mike Tyson in Punchout....

 

Lar, if you're asking about catastrophic failure, then no. Problems? Sure.

The wheel hub and CL mechanism is COMMON to all Gen 2 GTx cars down to the part numbers. The same issues that befell various unlucky GT3 owners can happen to us. You wouldn't expect otherwise given the fact pattern.

I would reason that CLs are safe in a laboratory setting where every wheel change is done to the tee as per the factory instructions. I thank the many contributors on this forum for sharing those procedures. Porsche should've done that from day 1 and not leaned on us customers as their guinea pigs.

In the real world, the inner wheel hub threads are probably very sensitive to over-torquing. After hundreds of wheel change into my ownership experience, there is simply no way to ensure EVERY SINGLE change was done with clinical precision. I am already OCD-level hands-on with my car in the pits but sometimes you just have to rely on others to do the job. And I'm genuinely seeing worrisome signs in the other thread I started two weeks ago.

There is no reason to be unduly paranoid, but knowing the latent issues with centerlocks it pays to be extra vigilant. Follow the inspection program every time your wheels come off. Replace worn hubs (even potentially worn ones) prematurely for peace of mind.

 

I doubt this has much to do with it 24Cr... If anything, the RS wheels are offset further outward yet same size as non RS, particularly in the rear so by my non engineer thinking, they should place even greater leverage on the attachment point...

Maybe RS owners follow instructions better?
