Every C4 Ihave seen lately is a 1/4" lower on the d/s rear. I have had discussions with knowledgeable people on this matter, but nobody can put their finger on it for sure. Bill B. (aka ZFDoc) once surmised it could be the bushing and/or alignment of the batwing mounting.

I can tell you that you are most likely barking up the wrong tree thinking the spring is weaker on one side. I have an aftermarket rear spring too, and though to test that theory... I flipped it 180 and the d/s still sets a touch lower. In the end, I just cranked a couple of turns on the adjusting bolt to help offset the weight of the driver and to get the level look.
