Am I too fat for GT3 seats??

The dealer? i don't think Porsche is allowed to sell those seats in the car stock.
DOT regualtions require that the seat have the ability to recline if I'm not mistaken. Maybe they have them with all the other Tequipment stuff in the parts department. But I'm sure you won't see them in a car on the lot.
That's why they call them Euro GT3 seats. Stock in Europe, aftermarket in the U.S.
If you can find a Recaro delaer in your area they are essentially the same as the Recaro Pole Position without the star trek shape on top.
