I put bbs rs onto my S the other day rears fit great drivers side fits fine but the passenger side wheel sticks out about an inch the in added as much negative camber as possible but there is still a degree of positive camber if you can pin point if and or what is bent I can use all the help I can get

 

Re align your subframe. Might be off-centered. Or a bad arm

 

Is that something that can be done at home?

 

Anything can, with the right tools

 

Are you the original owner of the car? Sometimes people buy a car that has had minor body work damage. When they repair it, they just slap on a new fender and don't roll it, so you have one wheel that sits correctly in the fender and the other doesn't.
