I wouldn't really recommend the AX pads for anything. I used them on a z34 for ax for 2 events and took them off, they have so much immediate bite on a big brake system, they are extremely difficult to modulate. I had to make a conscious effort to go into the pedal so slowly. Also they are likely not going to be heat rated for real track use.
No matter what company you go with, you'd be best served talking with whomever you decide to buy from about what tires you're running, what your skill level is and the weight of your car. This gives them the best chance of getting you best possible mechanical brake setup out of the box.
If you do go with Carbotech (which I highly recommend!) I've talked with Mike many times over the years for many cars and the service is always A+
I've got a fresh XP 10/8 setup waiting to be installed for regional SCCA TT in a few weeks which just so happens to be perfect for your car on 200tw~ish tires.
