IDK, but I am not a suspension guy either LOL. I think with lowering springs, OEM shocks and struts take a beating, and have to be replaced earlier than usual. Can't rightly say how much life is remaining on them. So I would really look at the value of the H&Rs alone. Plus any installation costs. Granted the fronts would be plug n play replacements (w alignment) because the springs are already installed in this ad so that saves time and money there.
