Anyway, if you don't want N-rated, get something else.  Porsche can't test every single X-through-Z rated tire out there and give approval of it, so go based on what reviews you've heard.  I've tried Kumho ECSTA 712's and they worked just fine - super cheap, too.  I've also done the unthinkable and put S-02A's on my car instead of the Porsche-approved (and identical) S-03's.  Dealers are supposed to tell you to get Porsche approved tires, what would you expect them to say?

I've read some good reviews on Yokohama ES-100's - I'm seriously thinking of trying them - TireRack likes them - excellent traction wet and dry and decent tread life.  Thanks for the comments.
