I'm currently on Z1 two piece, as well, drilled+slotted. If I end up with issues with the drilled, I'll probably just swap to slotted or sprinkled, only.

My buddy, Austin Hertel, went through two sets of z1 2-piece rotors in a matter of a few months (like 3 track days). Both cracked in the exact same spot. Z1 refused to replace the second set. He literally used up .011mm of the rotor when it cracked. I’d steer clear of z1 2-piece rotors if you track your car. Z1s “excuse” is that he used them in very cold temperatures lol.....
