Pressed my spc adjustable upper ball joint into the rear upper control arm of my ap1 last night . I set the ball joint for negative camber and it only moved a very small amount in the slider.I then noticed that the metal body of the spc joint was against a raised edge that is located on the control arm where the flat portion that the ball joint is pressed into and the portion of the control arm divides to two arms.is this the max ill be able to go or should I grind material off of the back edge or the joint or off of the raised area of the control arm?
