Hmm. I’d like to know if the Camaro uses the same 27-spline output shaft version of the trans that was used in 4th-gen F-bodies, or the 32-spline version that was utilized in the SSR. If it’s the former, then yeah, they’re going to break like twigs (I have personal experience with this in a 4000+ lb car with 400+ HP). If it’s the 32-spline version, then I would perhaps think that this is an issue with the quality of the output shaft and not a design flaw, as that should hold up to a lot more power than a stock SS can put down.

EDIT: Just saw a pic of a snapped output shaft. Looks like a 28-spline configuration (if I counted correctly while looking at an out-of-focus photo on a 10.1″ screen). That seems a bit inadequate for a car that weighs nearly 4000 lbs and puts nearly 400 HP to the rear wheels. But the surface of the broken part looked glassy-smooth, and didn’t seem at all like a properly-manufactured part that was overloaded. If I had to guess, this is the result of a material or manufacturing problem.
