Could you elaborate a bit on as to why the rear spring rate was increased so much (i.e. doubled from the OE settings)? If I understand it correctly (but feel free to correct), that means you run double the stiffness in the rear than the original Öhlins came with. 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.
