Ive replaced lower arm on my frst,but what I did was tighten up bolts and pinch bolt while car was of the ground,I know I should of lowered first then tighten up,I know they are Strecth bolts do will have to replace now anyway would this affect the camber the way I did it as the ball joint is rubbing on the back of the discs,the car has been lowered but I never had this problem while it was lowered on the old arms what have I done wrong!
