To the persons complaining about knocking, and not enough positive camber, have you checked to see if the ball joints are installed backwards??

I just noticed while installing mine, if the ball joints DO NOT have the SPC logo towards the outside, then maximum positive camber can not be achieved.
Another observation I made, with the ball joint backwards is the 27mm nut above the ball joint would sit higher and further out towards the inner fender radius.

Post your results.

 

i have everything installed right, and i was one of the many complainng about this problem, actually very recently. the 27mm nut was never the thing hiting my fender, it was the black metal directly in the outside direction of the nut, like the "corner" of the arm one could say.
