I do slotted rotors (Alcon) in that size but they are NOT cheap since they are full-floating and require different hats/hardware.

H iCarm:
The AP or Alcon slotted rotors run $ 1850/pr (floating or bolted) on the front. Rears are not available in that size and you'd lose the E-brake if you wanted a custom setup.
Cooling is critical when using these smaller rotors (305mm) on the track with these heavy cars so I'd also recommend that you install a pair of GT-3 Cup air deflectors on the front A-arms. You'll need to do some modifications to make them fit, but they help reduce brake temps.

. Would I be able to use the GTP setup on my car with 17 inch rims and if so can you let me know the cost of those?

Indeed, these pro-grade racing rotors are NOT cheap, compared to OEM ones, but the quality/longevity is in a different league altogether. No comparison.
GTP brakes will fit a 17" wheel with no problem and they are really a better solution due to much improved thermal dissipation capacity. In the long run, you'd be much happier.
PM'ing you the numbers.
