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 expect what you are feeling is the driving aids kicking in. They are simply doing what they are designed to do. Turn them off and do the same drive safely, then report back.
