When I bought the lower rear shock kit I asked about the fork lowering kit and the service rep at the dealer told me if you put the fork kit in you have to put the rear kit on. However if you put the rear shocks on you don't have to put the fork kit in(unless you wan to). I read the accessory book and it does say with the fork kit you need to use the lower shocks, but it doesn't say anything about if you use the rear shocks. Apparently the lower front end affects the handling, but the lower rear end doesn't?
