On the subject of camber kits, I offer up a suggestion.

A lot of front camber kits are brackets that install in place of the front upper control arm bolts. They change their length which pulls the control arm closer or further to the body of the car and thereby changes the camber. The problem with these kits is a lot of stress is placed on the bracket thingies and they don't necessarily hold their setting. Some people have also reported the brackets banging up the body of the car.

A better solution is a replacement control arm which has and adjustable ball joint. The control arm stays in place and only the ball joint is moved to adjust the camber. King Motorsports and skunk2 make kits like this.

For the rear since there's no steering to make the suspension more complex, it's a simple enough matter of using longer bolts to attach the upper control arms to the body and then using washers to space the control arm further away from the body until you get the camber spec you want.
