Hello Gents,
I have some issue in my 16 BRZ and have no clue about it

I was on track day and I did use the pedal dance method using my OFT and all good with traction fully off. My car has full exhaust, stage 2 oft, tein flex z, pmu pads with stock rotors and 215/45/17 toyo R888R tires.
The car is fast in the track, and Im really hard on the brakes. But during that day somthing I dont understand happend.
When I attack a corner hard abs light and slip light comes ON for 2 or 3 sec then gose off. right after these lights my traction control light gose off as I didnt do pedal dance or as I just started the car???? Forcing my to go back to pit stop and do the pedal dance again to avoid and traction issues.
It happend about 4 times during 3x30 min seasons 😐
Any have idea what happend??
