What you are seeing is an artifact of using the e30 semi-trailing arm suspension on the Z3. The static setting has a noticeable amount of negative camber (tires lean in at the top). It is like this so that you don't develop positive camber and squirrely handling under roll (the antics that made the Corvair famous).

If you lower the suspension, it makes it worse, and there are camber-compensating bushings you can use to correct for this. I wouldn't use them on a car with factory settings (and I doubt anyone who knew what they were doing would do this for you) as you could screw up the handling. This sounds counter-intuitive, but you could try lowering your rear tire pressure slightly, as a stiffer tire accentuates the outer to inner wear. Be careful, as decreasing the rear tire pressure can lead to an increase in the tendancy to oversteer, and a certian degree of this is already present in the semi-trailing arm suspension.
