Camber plates and adjustable (GT3) control arms are designed to give you MORE negative camber in the front. This is for racing and is not what you want if you're trying to get to stock specs. You should be able to get to stock specs in the front without too much trouble. The camber in the rear is the main problem. You'll have too much negative camber in the rear and can't really get it adjusted in without the adjustable toe control arm. It's not a huge deal. You'll just have a more aggressive setup in the rear, which will wear out the inside of your tires quicker. If you don't care much about tire wear, then don't worry. If you're worried, then get the adjustable toe arms. The ones from Tarett with bumper steer control are actually cheaper, not more expensive than standard. But be cautious, the bumper steer toe arms won't fit (I suspect) with some wheels - at least that was the experience with one board member and another manufacturer's toe arm with a similar design.
