Assuming you've got OEM rays wheels and no spacers, the wheels should be inboard of the arch. What does the camber look like if you crouch down and look from the back of the car? Should basically look like zero degrees as standard. The alignment could have got screwed if you've hit a big pothole etc, but that sounds a bit dodgy to me! I'd get it checked for sure - Abbey can do this for you.
The super pro bushes that Abbey also do are very good and will sharpen the front end of the car up. There's no additional noise from them, maybe a slightly more choppy ride, but they're well worth it especially if you're having new banana arms fitted anyway.
Glad to hear you're lovin' the Zed though!
