Is the hat on the wrong side of the ring?

Those rotors, what is the part #? Are they for a Gen 5 Camaro? Did you check the offset of the new rotors vs your OE ZL1's?

[IZM 1]

The rotors are for a Gen 5 (2012-2015 ZL1/CTS-V). They are Power Stop rotors, part of they Z26 Street Warrior kit. Kit number K679026, individual rotor p/n: Right AR82176XR and Left AR82175XL.
It is a BB upgrade from the stock SS 4 piston calipers on a modified 2011 SS.

[IZM 1]

The hat is mounted to the exterior (outer side) of the ring.

The calipers (GM) are p/n: 20982734 and 20982719
Manufacturer p/n: 172-2521 and 172-2522

The backspacing on the new rotor is 1.425"(36.195mm) and old SS rotor (with about 45,000 miles of moderate driving) was 1.210"(30.73mm).

Rotor thickness- new 1.340"(34mm) and old SS rotor 1.278"(32.46mm)

all that's missing is the caliper bolts (unless I missed yet another part)

New option for rotors. Brembo 2 piece, non-GM sourced.

I found this on Rockauto.com.

Brembo now has their own aftermarket 2 piece ZL1 rotors. They look identical to their same 2 piece rotors they supply GM with.

I have purchased them and they have the same vent design, vane count and the same hat and fasteners The finish looks the same.

Prices sometimes change on RockAuto, but they are currently about $170 each, compared to the GM sourced Brembos at about $290

It is possible that the cast iron is different, but everything else looks to be the same. As I mentioned, I have purchased a pair . I track my '14 1LE with the 6 piston front brakes and have no reservations with using these on track. They very well could be 100% identical but without the GM price surcharge.

interesting, i'm gonna have to dig more into this myself and see if these are pretty much the same thing just minus the OEM markup. i'm going to need a brakejob soon, thanks for sharing this. let me know your findings too.

actually the part numbers are pretty much identical to the ones on Brembo's site vs. RockAuto so i'd say this is legit

Picture of the boxes of these Brembo rotors. Rockauto normally does not use the zeros on manufacturer's part #s. I noticed this with Centric part #s also on their website.
