Just took my front rotors out for inspection. Lots of hairline cracks (normal) but I found 3 cracks going through the inner edge on the rear. I wouldn't have seen these if I didn't take the rotors off.
Last set of 355 rotors lasted me 14 HPDE events. This one was at 8. I'm considering moving up to 380mm and keeping my STR-40 calipers. This is probably against all conventions - larger diameter = more knockback, 355 to 380mm is 3lbs more weight.
Miatas have it so much easier lol
