I've looked at the picture of your rotors and it seems like there is still some life on them  I wouldn't worry about the hairline cracks until they reach to the edge of the rotors or they become very deep.
As I understand, it's possible to get about 8-10 track days out of OEM rotors and maybe a bit more with the DBA 5000s which is not too bad considering the weight of our cars |
What are your thoughts on what causes the cracking?
