if you use the cheep camber ball joints it raises you upper arm because the ball joint is huge so the you hit a bump and bam upper arm hits the wheel well(thy are fine if you are going for 1-1.5 of an inch but you are going for 3 plus the ball joint has to be pressed in the arm you just put in and go).the rears just use the adjustable upper arm i don't like the lower adjustable arm because that it where a lot of the lode is.
