Ok, so the "new" recommended castor/camber settings are for changing performance/tire technology etc... and are just that, "new recommended settings"! The factory service manual had + or - specifications for caster/camber for the given tires or performance level of the time, and the offset bushings allow you to "add" or "subtract" from those +/- specifications to increase the performance level for your car? Said another way, the offset bushings are not to compensate for frame sag or damage done to your car? Or, when an alignment shop cant get your into "factory" specs,or "recommended" specs and recommends the offset bushings its more than likely due to worn standard bushings? ....Im getting dizzy :blob:
