You have to decide if you want to go with the original alignment settings or tell the operator to use the settings from Audi S6+ or other performance oriented model .

The original setting is for luxury and comfort as I have been told. I have not seen the different numbers but I guess that the S6+ model use more camber in front and back and perhaps more toe in at the rear axle?

You will have more camber in front than original due to the lowering springs.

How are you going to use the car? Granny driving or curvy roads? Mostly highway or in town?
