I have heard good things about this Koni based system, but few of my buddies with these double adjust on previous generation M3's all reported ping and knock noises, have you experienced any on your M3?
I do have some noise when going slow over bumpy roads. I would not call it knock or ping. I had similar sounds with the PSS9s on my e46. The suspension is still excellent. I'm considering higher spring rates this spring.
