the front did nothing, i would put the bilsteins on the rear and see what happens.

i tried the kybs years ago on my saab. when they wore out after about a year, the failure was complete... as if i had no shock on the car at all. it was errie (sp?) i was going down a hill at a brisk speed and hit the little grooves they pot on bridges to evacuate water and the rear end started floating sideways as if on ice. no more kybs for me.

ditto for boges. they are better than kybs but not as good as bilsteins.

the bilsteins can be worn out and pass the traditional bounce test as far as ride quality goes.
