The time has come to change my absorbers, and I've been toying with the idea of getting a set of Bilstein B6, and a set of M-Sport springs (for the 10mm drop, that's all I want) I have heard that this setup may lead to a harsh ride once the suspension settles down. It is nice when initially installed, however, the ride deteriorates very quickly thereafter. Just wondering if anyone out there has tried this, and what your experience is? For context, I currently have the OE absorbers, with non-msport springs on my F30. I'm not quite happy with B8 and H&R springs on my E60, as I find it too low, hence, I'm thinking of B6, NOT the B8 for the F30.
