I have a 2011 GT500, factory PP car with stripe delete, the car is rated at 550hp stock. I'm looking for some opinions on what I should do next for this years mods. What would you do?

Here's what's currently done to the car:
- Pulley and tune by Sean Hyland - apparently 100hp
- Ford Racing resonator delete on air intake tube
- MGW shifter
- Roush upper and lower rear control arms
- Baer 2 piece brake rotors with 14" rear rotors
- VMP twin fan heat exchanger
- 2013/14 GT500 intercooler pump (higher capacity)
- 2013/14 GT500 open grills
- 2013/14 GT500 front splitter extension
- Ford Racing boss side pipe kit - psychological hp!

Option 1:
- Spicer 1-piece aluminum driveshaft
- Ford Racing rear seat delete
(Total cost approx $2500.00)

Option 2:
(Estimated 650-675 wheel hp)
- Ford Racing 2.3 TVS Supercharger
