Michelin Pilot Sport 4S tires, these are the front wheels. I'm unsure of the mileage on them, but they have 2 track days where I'm pushing them fairly hard. e.g. Novice group -- but tire traction is a limiting factor.
I just started my usual prep for COTA next week and noticed the inside of my front wheels look like this.
Camber is maxed in the front, which explains the wear pattern, but what is going on with the little pieces of rubber on the inside?
Link to image since the below one is massive and I'm unsure on how to resize it:
