Even the BMR engine mounts increased the NVH significantly, at least until the mounts and engine got warm. These engines are not famous for their smooth idle or operation : )
On my Miata, I ended up using mounts that are identical to OEM in looks, but with 40% stiffer rubber, and I'm very happy with them. I wish we had a choice with stiffer rubber for Camaros, too.
More importantly, Miatas also have a so-called engine brace option. It's an arm with a rubber bolted on the passenger side of the engine, and connects the engine block to the strut tower. It would solve your shifting issue (it substantially limits engine movement) without introducing any NVH.
Perhaps you should check out what is used as OEM on Z/28 and ZL1? I'd especially be hopeful about ZL1 mounts if GM upgraded them over SS, since they would be designed to carry more engine weight.
