I have got the 7 series cross spoke alloys off a 7 series on my '89 525 (they were on it when I bought the car). It seems to pull to the left hand side (towards the kerb, cos I'm in the UK!) slightly, although I have ahd the tracking and everything checked and it is all spot on. Could the wander be due to the slightly fatter tyres and wheels (tyres are 225/50/R15)? Alos, I'm guessing this is also the reason why the left hand front tyre is wearing the edge a bit quicker than the other one.
