They embellish it a bit, but in principle they are right. My local shop also pointed out that the wheels may need replacing at some point because of that wear on this inside. Happens when not torquing them enough but he showed me a Porsche bulletin which has it as regular wear. So having to factor in replacement wheels and the center lock components themselves (latter within 6k trackmiles at rear) is imv an unacceptable extra cost with close to zero benefit. We forgive Porsche for making such an otherwise great product though..
Invoice shows front rotors as well. Unless the front wheels came loose enough to damage the rotor surface there's just no appreciable need to replace fronts.
I had a detailer return my 997.2 turbo with centre locks tightened only to the "emergency" 100Nm. They had previously admitted they knew nothing about centre locks so would get the local Porsche dealer to remove and refit them. The nuts were flush and not buried (if that makes sense) and when I pointed it out they told me they must have been previously overtightened as 100Nm is written on the nut and they look much better flush !
Fortunately I spotted it right away and had the local Porsche dealer tighten them properly, before driving the twisty 2-1/2 hours home.
Does anyone think (as I do) this was staged for youtube? It's just too unbelievable to me that it wasn't. Someone disassembled the center lock nuts before they went back on the car? Give me a break!
At 2:22 they show a car with mag wheels and they say the rear came off. Even though it can happen... this was found on the Internet... and they do it for the clicks so a more reliable source would be better.
Ford dealer overtightened my lugs once and cupped the rotors. Same thing happened at Toyota. It was a real pain in the *** to prove it but both replaced the rotors. They just don’t care.
when new not many knew how to work them, I personally witnessed 3 cars' wheel flew off on track. I remember vividly b/c they almost hit me on track
I do not understand why ppl try to save pennies driving porsche
RTFM an DIY or send the car to a dealer.
not local tire guy.
yes porsche fkd up with this look good work **** design but some owners are not the brightest either.
I have my tires done by a tire specialist who provides support at some track events. At a recent local Porsche track event, they went to every Porsche with Centerlocks in the paddock and found that 70% of the cars had one or more of their centerlocks not in the safe/locked position (the center splined device was not popped out flush to prevent unintended movement).
If I need my Centerlock Wheel removed by anyone but a Porsche Dealer, I bring my Breaker Bar, my Calibrated Snap-On
Torque Wrench, and a tube of the Porsche approved grease. I supervise the removal, lubricate the parts myself
and set the Torque wrench to the correct calibration. I ALWAYS stay with the car until the entire job is finished
and make certain each wheel has been properly locked. I have even found unlocked wheels at Porsche Dealers.
IMHO, To leave Centerlocks to anyone unfamiliar with the correct procedures without checking them is suicidal.
And YES, they do look "racy" but I wish I did NOT have them also. A flat tire on a Centerlock wheel that can be
removed and repaired sufficiently to at least get you home or to a Porsche Dealer can be a real PITA.
Honestly, I don't get the hate on centerlocks. U know what I luv, when I goto the track and know everything is tight, because the locks prevent them from backing out. That said, I'm very careful where I bring the car... Just interviewed a well know Porsche shop in the Bay area and they passed, another extremely well known shop failed my test.
This guy is quoting 500 ft lbs...he doesn't know what he is talking about...it is 444 ftlbs...plus you must re-grease the Cl nut with Castrol Opti Moly grease...nothing else...torque the nuts wheel off the ground, back it off 1/4 turn and re-torque back to 444ft lbs...and make sure the hub lock spring device is all the way out with the tool that comes with the car.
CL nuts are a real PITA...I hate them....love the Gt cars though. No one touches my CL nuts except me...I check and re-check my indy shop, stand there watch, help so forth.
But maybe, just maybe they will be made out of steel like the cup cars, so at the very least, you could do a quick pit-stop type tire change with the big impact wrench. Otherwise, you have to wonder why this "feature" keeps getting imposed on us!

I barely graduated HS, but I presume it’s two fold. Buyers of GT cars for the most part, want to look like race car drivers on their way to C&C, and Porsche makes a fortune on replacement rotors and wheels.
