Our Nissan service dept. replaced our original rear Bilstiens with supposedly identical ones on my wife's 06 Offroad. (I'm pissed off because the old ones were fine and I could have done it myself in 20 minutes but that's a long story). Anyway, the new ones are worthless, way softer than the originals. I know these aren't "real" Bilsteins and are made much more cheaply than the real ones but does any one know if Nissan made them softer since '06? And if they did, what I can replace them with? Bilstein couldn't even guarantee that their 4600s would be stiffer or not.
