Emilio (949Racing) ran our 4-piston Front Caliper Upgrade on standard rotors on their orange ND.
Emilio is a monster behind the wheel, as anyone who has raced or ridden with him knows. We're excited to have 949 putting our kit through its paces. The pads they ran in the front for the weekend were medium/light duty track pads, and they hit the temperature ceiling on those. An avanced driver on tackday tires will need an aggressive track pad to last full sessions with standard sized rotors. Post-weekend reports from them on hardware performance show that the kit worked flawlessly, so I'm sure that with a pad change they'll be dialed in.
Alternatively, we ran our new BBK on the reflex blue ND all weekend with a medium/heavy duty track pad, and not only never saw an ounce of fade but we even all commented that we could have ran a less aggressive pad with confidence.
So, the standard rotor sizes are up to the task as long as you run a very focused, high-friction/temp pad for the track to handle those very high temperatures they'll be running at, whereas the BBK has more inherent torque and can shed heat so much faster that average temperatures are lower and a less aggressive pad is needed.

So what you're saying is- 100% normal, standard method for how braking systems work. I'm shocked 
OEM sized rotors, agressive pad and shortened life spans.
Larger rotors, longer life pads and/or ultra aggressive pads not needed.

And yet, somehow it is a revelation that needs spelling out to some... (not this crowd)

But what about the OUTRAGE of Mazda willfully trying to kill their helpless, innocent customers just to make an extra $52 in profit per car? Why would you bother trying to understand something when you can just pretend to be an expert and toss blame around?
Nevermind. For a second there, I forgot that I was on the internet.

Someone who was at MRLS is pondering why he was 5 seconds slower than Randy Pobst for Motortrend; he's sure it's the tires.
Pobst drove a (poorly) swapped 1.8L Miata at a Chump Car race a few years ago and was about 2 seconds faster than everyone else (including the car owners) on a 55 second course. Maybe being a pro driver might mean something... maybe...
I do wonder exactly what tires Pobst was on. I couldn't get below 1:55.0 in my ND on Friday on stock street tires. They just turned to goo after about 4 laps. Then again, I'm not a top race car driver (not even close...).
I'm still wondering if they used better tires for that. He's a great driver, no doubt...

D-K applies to race drivers; "I'm on the ragged edge of control, chewing up tires and eating brakes so I know this car can't go any faster. That other driver must be cheating/has better tires/has more horsepower.."

He is a scronny little dude.
Edit: dammit I knew that word didn't look right.
Scrawny indeed.

ND RZ
Ryan driving the GWR ND -
Blackbird Fabworx ND RZ roll bar
That's a 5'11" driver with a helmet sitting on a bone stock leather seat, roughly flush with the bar and ~1" under broomstick.

^^^ Nice pick up. Review?
