I will admit that poly bushings can improve defelction some over rubber bushings but my point was that for road racing, GM already engineered suspension pieces that are more than good enough. You would gain more from taking track driving lessons than from swapping suspension components on these cars.
As I stated before the cradle lockout is a necessity for better performance except on the 1LE, the other parts not so much.

I'm catching up to this conversation and can understand your viewpoint. However, here is a video from BMR of an SS, showing lots of suspension flex from the stamped control and trailing arms. On a Zl-1, the flex is much more:
I'm going to disagree about the suspension pieces being engineered as more than good enough. GM engineered the suspension to a price point. That's why the BMR pieces make such a significant improvement when they are installed.
As far as Hellcats breaking BMR pieces, I can't speak to that.
