Hi,
Yes, it seems B6 DT is not a happy compromise for comfort, even more so when taking into account I'm riding on 225/45 R18 NON runflats.
It's likely that comfort on 19" or 20" wheels, or runflat tyres, will be worse.
Before trying B6 DT I had Bilstein B16 PSS10 Comfortversion installed for a
very short while. These dampers are not controlled electronically; damping force can be changed through a wheel underneath the dampers. I haven't mentioned this because that's not the subject of this thread. Anyway (long story short) : the springs that are included in the B16 PSS10 set helped me decide to go back to the original springs.
So, to clarify, I went OEM -> B16 PSS10 -> B6 DT -> B4 DT.
Yes, I know, I spent some dough looking for a suitable suspension system.
But hey, you only live once. And , I've learned a lot.
Cheers,
GSband
