I have no idea on how to figure out camber, but assuming you did not adjust camber and remained at stock height, the lip of the rim will stick out 6 mm past the bumper and the edge of the tyre will stick out another 13 mm past the rim.

Feel free to flame me if this is irrelevant information.

Not sure why you would want to run no camber in the rear.

Please inform me why I need camber in the rear. (Like more than -1 degree)

I see what you're doing there lol.

I was wondering the same thing
