Wow, RC, thanks so much for the pics. As always, you provide 10 times more info than Porsche.
Asking anyone at the dealer about the powerkit parts was futile, as was trying to call PCNA. When I took my car in for its brake problem last week, the first thing the service advisor said was "wow, those brakes are HUGE, - where'd you get them." When I responded that I had taken delivery of the vehicle at his dealership 6 weeks ago, all he could say was "Oh, I've never seen one before."
