A question regarding the cross drilled rotors..

[adamt]

The car has done 2k miles and i was cleaning it the other day when i noticed that around the cross drilled holes there are some really small little cracks. I have seen this on turbos with much more mileage. But i hadnt expected it to happen so soon. Why does it happen and also does it affect the braking performance..

Any info would be greatly appreciated, cross drilled rotors are new to me
