Have you checked your ride height from one side to the other? Doubt it would cause that much of a difference, but worth checking.

Yes. They are only about 1/8" or less difference left and right. The driver side slightly higher.

I have about 5mm difference between my left and right strut shafts in the tower hole. Both were identically aligned (zero side/side variance) and it was either 5mm or 5.5mm difference. The driver side on my car needed to be that 5(+)mm more inboard to get identical specs.

I think it's probably just tolerance stacking.

Interesting. Can you explain what you mean by tolerance stacking?

One possibility is that you have some tilt in the chassis. If one side is low & the other high, that will make the situation you're seeing. If you measure ride height (subframe bolt heads are usually a good point to use on the car, but I'll have to look for a clear recommendation) from a flat surface, you should be able to see this.

All cars will have a certain amount of twist. If you can adjust the front ride height to be flat (with driver weight & 1/2 tank fuel) and take whatever twist that exists at the rear, that's about as good as you can get.

I would think it's got to be pretty close to even with me sitting in the car since the driver side is about 1/8" taller than passenger side without my weight. But this seems in line with typical lowering springs. You're not gonna get exactly equal ride heights on all 4 corners, at least I don't think. Unfortunately no way to adjust ride height let alone corner balance without coilovers.

I know this is an old thread, but did you guys ever figure this out? I am dealing with the same thing.

I never figured this out. I gave up - car performs fine.

Just saw this pop up. I'm on my second S550 chassis now and both have this same situation. I think it's just tolerance stacking.

So basically either don't worry about it if you're happy with your numbers. Or if you're feeling like it, you can shift the front subframe. Or install upper knuckle bolt eccentrics.
