In the front, since the damper mounts to the knuckle itself, it has a higher motion ratio and the damper travel is much closer to the actual wheel travel.
Good point and probably why bstops are way more critcal with oem and aftermarket static dampers - as a way of stepping up damper bump response as rear springs compress.

With adjustable dampers, the bump response can be tweaked so bstops role is more to prohibit bottoming out. Chopping the bstops on my car has worked a charm but I wouldn't recommend as a default mod for everyone.
