I remember reading this
I remember reading this article last year and thought at that time that Chevrolet was going to provide these upgrades for those who were looking to make their ZL1 faster.
I have a 2018 ZL1 looking to make sure the Mustangs stay in my rearview mirror, however, now that the gt 500 is running mid 10's from the factory I guess I will need to source these upgrades elsewhere, It would be great if the Chevrolet Performance Division would offer these upgrades. I may have to get a Mustang...
