Variation in Ride Height

Is this just a case of the springs wearing more on one side than the other from driver weight, equipment, etc.? If so can't you just switch the springs from one side to the other? They should even themselves out if that is the case.

No, these are new lowering springs from H&R. My tech did not measure prior to lowering, so I thought my car was f'd up from a curb I hit. I am glad this is not the case..........

Turns out, this is "normal", even on stock cars. I am anal, so I am thinking about leveling it up by cutting the right side spring a bit. Not a huge diff, but I figure this could be the reason why with a perfect alignment, I have a pull under braking.
