I've got the Z1 cross-drilled and slotted rotors. They made it through the Nismo Performance Academy at COTA and some pretty spirited drives with zero cracking.
If I was tracking a lot, it might be a different story.
As soon as Z1 has the two-piece rotors available for the rear, I'll probably swap out all four.
