OK so last night I sent a note to Carbotech and this morning I have already received a reply, below is the exchange. Thanks for the recommendation to contact them direct. Hmmm maybe I'll look at the spec miata set up of XP10 front, XP8 back...Or not

Hi there, well after asking everyone on Miata.net and GRM, some one suggested I go straight to the source.
I need new pads and rotors for my 99 miata, with Supercharger, Flying Miata springs and Illuminas, racing beat bars, running Kumho XS 205 50 15's
NASA HPDE 2 at Roebling Road. Full interior and not a small driver, so about 2400lb if I remember from the last time I was on the scales.
I was thinking new rotors, and XP8 on the front with 1521 rear. Once back from the track days I could go to 1521 all around, for autox and trips to the beach.
What are your suggestions? Also can I use the same rotors on the front for the XP8 to 1521 swap? Of course budget considerations are a factor..
Thanks for your help,
Hi Richard,
I would recommend XP10 up front with your 1521 on the rear if you are only running Roebling Road. RR is an easy track on brakes so you can get away with running a front track compound only. But, with that supercharger and other modifications I would not recommend anything less than our XP10 compound. Yes, you can run the same rotors with our 1521 compound and XP series compounds. Let me know if you have any other questions. Thank you.
Last bit note from John at 5x was suggesting the AX6 for the rears, can be a bit much on the street but will work well overall.
I'm guessing it's time to pull the trigger, let you know how it all comes out.
Interesting that they mentioned using a street compound on the rear with something as strong as the XP10 on the front. I've never owned a Miata, but are they that heavily biased towards the rear?
I don't know if their brake pads are any good, but the chick selling EBC brake pads on SpikeTV gets my business.
So after consulting both 5x racing and Carbotech, I went with the XP10 front and AX6 rears, which in their opinion would hold up to both Roebling as well as RA and my dream of someday Barber. Once home and done, I'll get a set of AX6 for the front for autox and the occasional trip to the beach. Most think the AX6 will work on the street as long as I can handle the noise. If too much I'll just have to head to NAPA for a set of street pads.
Got the centric rotors as well and will do my best to bed them properly. Now got to find a place in Pcola where I can accelerate to 60 and then brake to 5 a half dozen times or so right?

I think the idea is the miata is pretty easy on the rear brakes, there fore I could get away with the cheapest set up by going to lighter pads back aft. In hopes that I can get to other tracks that are harder on the brakes than Roebling I went ahead and got the AX6 pads for the rear. It was a difference of $11.
Price with taxes and shipping was the same as 949 with shipping but no taxes. So seeing as how 5x had put the time in I felt they deserved the business.
