The thread in which we discuss NC brakes
I think it has been too long since we had an NC tracking thread.
Gingerman 5/11 Miata Meetup. Intermediate run group, 1:47 pace. Compound fade from EBC yellow pads within 1-2 laps. New rotors were installed with the pads, system had fresh ATE200 fluid flush before the event. No brake cooling mods.
Speaking with multiple others, theoretically this should not have happened with pads rated for 900*C. I wouldn't call myself particularly hard on the brakes, as I still see a lot of time being lost braking too early.
Anecdotally, I have also heard from some that EBC yellow is terrible garbage and I should throw them away ASAP as they are 100% to blame. I really don't see myself getting the brakes over 900*C with a largely stock car with only 160whp on a good day.
Who can add data points for NC brakes?

Ebc yellows are just that bad. I bet chunks are torn off the pads already. I barely got three events out of them on a stock NA.
Advice from this forum:
Advice from this forum:
- Add real track pads from real brake pad companies.
- If those aren't lasting long enough or over heating, add ducting.
- If forced induction, add BBK.

EBC yellows only lasted 1.5 days on a stock NB2 with coilovers and 195 AR1s, while giving such a low mu that the ABS would come in because the line pressures were so high. 610C rotor paint didn't turn instantly (though it did turn), so I don't think they were that hot.
I spoke to EBC technical support at the Autosport show (UK's version of PRI) and they denied that a Miata could ever generate enough heat in the brakes to warrant one of their racier compounds, despite me having the data to say that it did.
Carbotech XP10s lasted so much longer that even the huge price delta in the UK (£210 for front pads alone vs £65 for EBC), it was cheaper per lap to run the XP10s, along with the benefit of brakes that actually worked.

Why take the risk? Several of my buddies tried EBC Yellows when we started tracking. 1st gen boxster, S2000, NB Miata, E92 M3, 370z. Not one of us will run those pads again. They are the equivalent of Hawk HP+, which no one recommends for the track. Hawk DTCs would be the same price for the NC.

I was riding both times, driver is advanced level. He had brake fad by lap 3 session 1 on yellows and had to do cool-down lap sometimes even coming into pits early. PFC 11s lasted all session, deeper braking points, and better modulation
Yellows just shouldn't be a consideration for a track pad.

I'm not really sure why a bad experience using DTC-60s on the street is relevant to a thread about brakes for the track, in the race prep section?
Brake use varies pretty widely depending on the track and on your driving style, if you're fading the pads you have then you're getting them above the ideal temperature range. Your choices are better brake cooling, higher temp pads, or brake less.
