And this was after 4 sessions on track with the stock settings...
Starting to spit off chunks of outer tread blocks like mad. We monitored tire pressure - it wasn't that, it was just loss of dynamic camber.
We added -2.5° camber to the front, swapped tires front to rear, and the problem is solved. After tracking it all day not only did tire wear look 500% better we dropped 2.3 seconds per lap on the same tires.

Thanks a lot, that is awesome input. Those tires are completely different from what I have though:

I bought these tires specifically because they have very large shoulder tread blocks (same as re003) which I am hoping will help with the chunking issue. It is also a cheap and high treadwear tire which keeps some of the playful and fun character of OEM tires.
Did you use 2 sets of camber bolts, or some other method to get 2.5 camber? Might as well go that route before I wear out the outer shoulders on the new tires.
(Edit: Nevermind, I saw that you were using camber plates in the video.)
