Does this not affect the ride quality in a negative fashion?

And: What would be your recommendation for a 335i (which is slightly heavier than a 135i) for street and moderate track use?

I'm very interested in this, as I'm not so happy with my current Bilstein coilover.

It has to be with the motion ratio of the spring. It sits much further inboard than the front springs.

400F and 800R would be a typical dual purpose setup, but that will depend on your particular needs and suspension setup.
