Some basics to consider are that front springs/schocks are at an area of the chassis that is pretty constant in load where as the rear is subject to a much more pronounced variance of load from occupents weight plus fuel and /or trunk/bed loadings-the rear of a coupe/roadster(2 passenger vehicle) with 2 passengers can vary as the passengers could be say 200# each and fuel load easily vary 100 more lbs plus trunk weight (chairs,cooler,xxx) the front loading won't be effected as much----------this will most likely result in shock settings that are considerably different rates compression/rebound front to rear????????
