Interesting that the 911 GTS isn't included on that list since they have the locking center hubs also standard but maybe they fixed the problem before they launched those...
The notice states affected cars were built between May 18, 2009 and Sept. 17, 2010, so it's likely the GTS' weren't being built yet...
