Having been made aware that there's a big problem with these cars, it's only right that I show you the answer:



This is the K-Mac kit for rear camber adjustment of the Saab 9-5. Also available for other models.

The serrations in the end of the bush are hardened so they get a good grip on the links and don't turn once the camber is adjusted, the urethane runs in a steel outer shell and is able to turn for adjustment.

No shims...
