HOWEVER, based on the most recent track (hpde) feedback on here, it is not sufficient for serious track use, esp in warmer temps. You'll still need an aftermarktet oil cooler like the Z1 unit I'm running. The vendors here are going to need to make a kit specifically for the '12+ z models since the ones for the 09-11 z's won't directly bolt up. I'd call Z1 or GTM etc and ask what the eta is on it.
