if you have camber pins on your car 0 camber is posible, thats what i have one mine with the spacers installed, the upper control arms are made off a jig of the original arms so camber is not affected when installing these. im not sure if they are for sale yet but the same guy is making lower control arms that are adjustable for castor and camber, but it also raises the whole strut by 2 inches giving you a lift without the need for the spacer. if people are interested i can look more into it. it would be a good idea for those with spain built trucks that dont have camber pins
