I got 3 track days and 1000 street miles out of my tires before the insides corded. I set the alignment each time back and forth and still corded the inside of the front tires. However I spot drilled my tires to check depth acrossed the tire before hitting the cords once the insides were toast..

Inside to outside depths 0/32, 2/32, 4/32, 2/32, 1/32

In all reality my outside edge was about to cord also and the only way to fix this is to run higher air pressures. I was running 36 hot. and normally started around 28ish cold.

I have a track day the next two weekend which will consisted of 3 track days. I plan to start 30 psi cold and shoot for 38 hot. we will see how that does
Below is my tire data from one 20min heat
