ZL1 Rotor Fitment
I have a set ZL1 rotors that are measuring almost 15.5 inches across but according to ROCKAUTO.com they are supposed to be 14.3 . ZL1 and the CTS-V are the same size (currently running CTS-V rotors with ZL1 calipers. Trying to figure out what these rotors are from. The hats say 7 Jun 07.
So when I install them the calipers won't bolt up. Is it possible they are Z28 with steel rings??

Did you possibly end up with 6th gen ZL1 1LE or CTS-V3 or ATS-V rotors? The offset would be very different Howeber. The gen 6 ZL1 and the ZL1 1LE supposedly have the same caliper as well even though they are slightly larger diameter rotors.
Does the offset appear to be correct and only problem is the diameter? |

Offset looks good, its the rotor diameter that's to large and the hats have a 7 June 07 date on them. Member I bought them from said he pulled them from a ZL1.
Looked up C7 Z07 Corvette Front Rotor Dia and its 15.5 I think someone did a lot of work to a car and wrecked it.

My set of CTS-V2 two piece rotors say 3Apr22 9:49. So that’s not a year in yours. It’s a shift or hour or Julian date or something internal like that.
