Couple of recommendations:
- Consider the GTS interior package. It is a unique package that would increase resale value
- If you intend to track with the car, I'd leave out PTV
- Consider sport suspension if you don't mind a little harshness during DD work. Porsche is very good in shock calibration, and the sport suspension is probably the best they have come up with thus far. And the additional 10 mm drop in ride height makes the car's stance perfect even though on paper it is only 10 mm, the look is brilliant. Although it can be retrofit later on, the labor cost (not parts) will be more, replacing the A/R bars are a PITA.
- Unless it is for visual reasons, PCCBs are not worth it on a Porsche as the steel brakes are truly superb. However, after you get your car, consider installing GT3 master cylinder for improve pedal feel and track duty.
Best of luck and enjoy the new car.
