i read a review that talked about how the a-armed style camber kits can have alan slippage and possible boots ripping on the ball joints. I know with the more conservative camber kits that just directly attatch, rather than replacing the a-arm, couldnt have those things go wrong with it. My buddy swears by the cheaper ones that just push out the assembly by twisting and says they are more reliable and do the job, and most likely last longer. Throw out some opinions on this
