I don't think there are. I believe the FE4 has a slightly different link in the rear, but it's not part of the 1LE Handling Kit.

The strut mount for the ZL1 is probably the same as the 1LE since they are both listed as FE4 and the ZL1 1LE uses a completely different mount.

Good point, but that's not he difference between those two. The ZL1 vert uses 84186926, code AA3N.
The 6th gen Camaro is actually pretty awful for spring codes as well, mostly on the rear end though. I feel like I have a
reasonably good grasp on the front spring codes for our cars, but the rears are almost a complete mystery to me. According to all of the fitment info I can find online, the code of the springs that I found installed on my 2016 2SS Coupe with MRC should be for a 1/2LE or 1/2SS coupe w/o MRC. But here they are on my car for some reason (and with an RPO code to match).
The problem is that they have so many spring codes for the rear, and they use some mystery "computer selection" in the factory to pick which one they use. Even the ZL1 has AA0B, AA0C, AA3M, and AAZ9 (that I know of). According to the coding, the AA3M is the only one used on both the ZL1 and the 1SS with FE4 (which is a coupe), so that's why I chose it for the list above. The other three though are just coded for "ZL1", but with no additional info. One is probably for the 'vert, but what about the others? Why would there need to be more spring rates for the ZL1 (non-1LE)?
This is why I'd really like ZL1 people to start posting their RPO stockers here

. We can translate from the codes starting in 8 and 9 (eg 8AT and 9AT) to spring codes. With enough different samples, we might be able to figure out which codes go with which exact option combinations.
