DBA Rotors ???

I've got DBA 4000's front and rear on my C6Z.
They've got 5 track days and about 10,000 street miles - all with Hawk HP+ pads. The rotors look perfect.
I'll be going to some race pads for several events later in the summer and in the fall, so I expect more rotor wear with the more aggressive pads.
So far, so good!

All iron rotors, when used hard, develop tiny surface cracks that grow in depth and length with each heat-cool cycle. Eventually they get large enough to crack the rotor all the way to the edge. It is wise to change them before they get to that particular stage of their service life.
If you haven't seen your rotors do this, you have not been using them hard enough.
Hope that explanation helps.

Never tried them myself, here's a thread from another forum though - FWIW.

The best thing to do with new rotors is use them on the street AS MUCH as possible before your next track day and they will last significantly longer at the track. The more low heat cycles you can introduce to them before a hard track day, the stronger the metal becomes.
I drive my Corvette actually during the winter and I still have the same rotors on the car after 6-7 track days with just minor cracks and these are C6Z rotors with the holes.
