wheel alignment adjustment options
 

I'm taking my SVX in for a 4 wheel alignment tomorrow. I have looked at the Chilton's manual, and it appears that for the front end, there is toe and camber adjustment options. For the rear end, there appears to be an eccentric bushing in the rear lateral link where it connects to the subframe. I can see this bushing affecting both camber and toe. Can anyone tell me for sure what this eccentric bushing adjusts?

Thanks!
