First HPDE: Squealing noise in turns during last run
On my last run, I had forgotten to disable traction control until about 2 laps in. Around that time (maybe after another lap?) I started hearing a whining noise in the corners. At first, I wasn't sure if it was coming from my car, but it did seem to be coming from the rear. I wasn't on the brakes during at least most of the time I heard it.
Since I started to hear it more and more, I got concerned and pitted in. That was my last session for the day.
Is it possible that traction control overheated the rear (stock) pads and I was getting some dragging, even when I was no longer on the brakes?
I also wonder if it could have been the rear diff, since it was always in the turns.
I have not heard any strange noises since that time, and there's plenty of material left on my pads.
