After this, even though I have two degrees in mechanical engineering, I'm done with trying to do better than the thousands of hours BMW spends in making the ultimate driving machine in tuning their suspension...hard to compete with that.

On smooth roads, you can get away with almost anything, but physics are a pain, there's only so much you can do between spring rates, damping and bushings...active suspension is an attempt to cheat physics, which may be why DHP is the route BMW went with the X3. If there was a way to make an M3 take bumps like a 7 series, it would be done...but it can't be done, until active suspension advances a bit more where the front shocks can react in real time.
Read up on the McLaren MP4-12. That suspension and damping system is out of this world.
