It's always difficult to determine if the springs are the culprit without removing them and testing them on a machine.
Furthermore, it's also difficult to state with accuracy that the vehicle "sags a little". You need to remove everything from the trunk and take a look to see if it's level when you've got it on perfectly level ground. A full tank of fuel will affect the results.
Typically, most of us carry some things in the trunk and, with full fuel, they will never be quite level. Not much you can do about it unless you start out with the vehicle "too high" to begin with.
The least costly item that has the most effect is the differential mount. If it's original, it will give 3/4" of additional height.
The second least costly item is thicker spring spacers above the rear coils. If you are not at the maximum thickness, these can also give another 1/2" or so.........depending on where you start.
The final item is the springs.........costly for sure.
