FWIW (Not Much)
Back a few years when starting the build on my Camaro looked into this. Spoke to S&W was told the anti-roll bar was approved, had to remove the stock fuel tank. At that time did not want a fuel cell and was more interested in what AppleTree Engineering offered.

The ad seems to assure/infer that it is approved for Stock.
Would think that with this thread and comments from tech officials Scott would be looking into this. Am sure he would not want to put any of his customers in jeopardy.
