'97 540i sport suspension alignment questions

This car has the sports suspension which is great, but I had it aligned on a
Beissbarth Alignment system and now the new front tires are wearing odly.
The front right inside and front left outside of the new tires are scalloped
after 5500 miles. It was set to the factory specs which is a slight positive
Toe on front and back. On this system it is +0.08inch total toe. The last
set of tires had 40,000 miles and they were perfectly square and even worn.

What would make it wear on the left side of each front tire? Anyone have
troubles getting set correctly.?

Maybe wrong camber? Asymetrical wear like you describe can't be from wrong
toe-in and would result from some other misalignment.

When the alignment was done were the control bushings checked for wear?

The instructions said to use Windows 98 or better, so I installed RedHat.

Jim,

The front struts and one control are was replaced since it has 115000 miles
since the bushing was bad. The camber was set to left -0deg 15min and
right -0deg35min.

At 115k miles I'd expect that the control arm bushings on both side would
need to be replaced.

Was the alignment done with the car weighted down per BMW specs?

Jim,

The other bushing was OK and it was weighted as specified.

Well, if there are no worn suspension components it seems to me that the
camber would have to be wrong to get that sort of wear.

Probably something else is also worn (perhaps the other side?) Those
camber settings sound a bit "upright" to me but i don't know what the
facotry spec is.
