on a brand new black edition your good to go........have you tracked before? the reason i ask is your really only gonna see the cracked rotors after multiple track days with alot of heavy high speed braking that gets the rotors really hot... GTRs that are new to tracking or even occasional every few months probably wont see the abuse that starts cracking them.....
also its a little too early to tell but the 2012 has larger rotors that nissan said helps dissipate heat better...so its possible these could be less prone to the issue... although its really the design of the drilled rotor more than anything thats why most switch to a slotted/vane or j hook pattern when its time for new rotors
