You don't necessarily need camber plates. If you get an alignment after the install, they're going to adjust your toe which will have more affect on tire wear than camber. But if you want to run the same spec as stock, yes, then get camber plates. But then you'll be shoving another $200+ for them and your from will raise another 1/2". But then again, with a small drop, it'll barely change the front camber. As for the rear, a stock MS3 already runs rear camber.
