What about B4 vs B6? Has anyone used the B6, does it degrade the comfort a lot or is it a better quality damper circuit so more control towards full travel without introducing excessive impact harshness? Too many potholes around for high damper forces as far as I am concerned.
The Bilstein website is no
help, it talks about 'damping power', not sure which marketing numpty wrote it but dampers give a force, the magnitude of which varies with the damper shaft velocity. The only thing power related would be the heating of the oil as it is forced through the control circuit but this isn't usually the way dampers are characterised.
