Back ground info that may help:
- tires are ad09r 255/35/18
- brakes were not hot at all
- pads and rotors are standard gts but with braided brake lines and standard fluid
- driving aids were still on
Anyone have any ideas? I have my first track day in 2 weeks and there are some very unforgiving walls near braking zones there so I would like to get this issue resolved.

I'd first verify ABS is doing what you expect. Force it to engage in a safe place where you can stop HARD in a straight line. Stay in it. It's tough on pads, but the car should still stop rather quickly - not quite as quickly as if you'd not engaged ABS, but close. Once ABS hits you need to use maximum force on the pedal for it to work at its best, unless you have room to release the brake and re-apply with slightly less force, hopefully not hitting ABS.
I don't recall ever running into the nannies under braking, only after releasing and while turning. Doesn't mean it doesn't happen, of course.
Could also be EBD, which only goes away with pedal dance.
Nannies off can definitely help, but you have to be on your game.
