I've done a search already but haven't found what I'm looking for. I know that if I take off these there will be more noise and potentially a harsher ride. So what I want to know is would it be wiser to put on the top ones and leave off the bottom ones or the other way around? I'm using the c springs and don't want to cut a coil. I know some people don't use the insolators, so what do you guys suggest?
