They are extremely easy to adjust. All you have to do is loosen the three upper strut mount retaining nuts. You don't even need to unweight the suspension.
But my personal opinion would be to set it and forget it. You can get a pretty "aggressive" alignment (read: autox oriented) and drive around on it every day, on soft tires, like the Dunlops with no adverse tire wear.
