We will post more info and pics when the conversion is done this week.
We did consider both 5 lug and Cup CL, and choose to go the Cup CL route.
Yes, all hubs and nuts or lugs or whatever have a defined "life cycle". With our experience on the Cup car, and the technical docs you get from PMNA on the service of all parts, this gave us the confidence that this system would work fine.
The cost to do either 5 lug or the Cup CL is almost exactly the same.
We also liked the wheel selection options.
Just as an FYI, you can NOT run Cup uprights w the Cup CL integrated...you have to run just the hub section.
As w the 5 lug, you need to do the wheel bearings...replace them. These should also be done on a regular basis even if you run regular stuff...don't care whether original CL or 5 lug or Cup Car CL.

about as many people can handle the Cup Car CL's as can handle the current Consumer CL's - all you need with you is the Cup Car CL socket - a simple matter of giving money to Porsche Motorsports…
the Cup Car CL's should hold up just fine in street use - although that was a minor consideration given that the car is now mostly a track dedicated car.
as I said at the beginning of this thread - "my opinion" is that the street center locks have problems and I've yet to see any evidence to the contrary for the cup car CL's or the 5 Lugs - in my opinion wheel attachment points should not be subject to catastrophic failure under normal track use conditions - as to porsche's assertion that properly maintained CL's will not fail - proving improper vs. proper maintanence is steep hill to climb.
when I started this thread I knew of 3 failures (a high number in my opinion) having reviewed other forums I now know of 6 failures of the consumer CL systems in HPDE/track use - that number is way way too high IMHO.

Dave04Porsche - I am considering updating my 2010 GT3 to the Cup Car center locks also. I was wondering if your experience with them so far has been positive? Any concerns? Any current feedback would be great. Thanks.

no problems so far on the Cup Car Centerlocks - the only issues remain this is a damm expensive swap given that no matter what direction you go (5 LUG or Centerlock) you're in for purchasing new wheel sets. Also since this thread was started it's now a fact that Porsche recommends timing out the Street CL's every 4200 miles if they are used on the track - that's expensive to keep that up on their schedule.
Cup Centerlocks are not street friendly and technically a fussy person could ticket you for using them on the street. Unless you have mitigating circumstances (like I do with access to other people's 18" cup car wheels) I would recommend 5-Lug conversion because of the simplicity and long history and familiarity people have with that system. Not due to problems with my Cup Car CL's - just due to the fact that they are "still" different and only understood by a minority of the automotive community.

The number is very small as a percentage of cars sold and tracked a cross the globe, all cars have hub, bearing and wheel attachement problems that equal the forum numbers. Furoms are a risk place to take any facts and numbers from period.
I know of 1000's of 5 lug issues (other makes). Where track use is a problem is the frequency of wheel removals (pads, tyres, inspections etc) combined with a re-torquing procedure that cause some problems and any errors can be catostrophic in nature.
