Has anyone found an performance based harmonic balancer for the S65?

I keep seeing the benefits of ensuring the reduction of torsional vibration to the engine and bearing. Since S65 has bearing issues wonder why I can't find anything on this.
I am confident the answer is "no". The issue has been resolved and is simple - replace the rbs.

While it doesn't change the ultimate answer, wouldn't a harmonic damper be more about the main bearing on the crank? I had an ATI on my MINI Cooper S just because.

Well now you've taken it way past what is and will ever be my technical knowledge :)
Has anyone had any experience working with the harmonic balancers or found a suitable aftermarket?
