The bulletin says that the only hardware change to the suspension is the new springs, but it's safe to assume that BMW is including other changes to account for the new spring rates, right? New shocks, bump stops, guide supports, etc? Or are they really only updating the springs, and will it be as simple as ordering those springs for those of us who want to retrofit the suspension on our cars?
