Very common problem on the LSA. As previously mentioned it has been know to happen on stock boost. I just had mine reinforced this past fall. $32 for the aluminum plates and $60 for a local shop to weld them on ("local" it was Steeda lol). The biggest pain in removing the s/c lid due to the 6 rear bolts under the cowl. Other than that it's a super easy and cheap mod.
And yes, the CTS-V brick is slightly different than ours due to lid design. So in your searching make sure you get the ZL1 specific plates and/or brick.
Here is some good info about it:
