I would not go with 19" wheels. Fewer tire choices at higher prices. Lose lose.
Tire companies love increasing tire prices big time for just a tiny bit more rubber.
Incidentally I have 18" 997 replica wheels and they are too heavy in the back for this car. It slows the car down from a stop.

take a look at the Forgeline choices in 18". They are probably the lightest wheel at that size. Lighter than the factory Carreras.
