Default Cracked brake rotors

After only 2 HPDE track days with NASA I had cracks in both of my front rotors. The rears still showed the cross hatch machine lines. I know I was using the brakes hard , but I think the rotors should last longer than this. What rotors have you others used with better results?

I have been using DBA 'Disc brakes Austalia' they are heat treated but after one evening of 5x5 laps i can see the start of small heat cracks so I know they will only last one decent meeting before a rotor ends up with a decent crack that will require a rotor replacement, pissed off they don't last long enough

Wilwood in front (complete aftermarket setup), EBC in back (1998-2002 f-body directional slotted rotors), no signs of stress anywhere.

Small cracks are normal.

The only thing you'll go through faster than rotors is gasoline.

Trouble is that once they are there I know they will get bigger as the rotor is already compromised.
From past experience I will get only one more meeting before having to replace them 'AGAIN' this will be the 5th set.
