if you're gonna adjust your ride height at all, you're gonna want to get it aligned. Toe in/out is what wears your tires out, not so much camber. But yes, I would invest in a camber kit up front if you're gonna slam it, as far as the rear, just get a home depot camber kit, worked great for my old hatch, I've never had a camber kit up front and my old hatc was pretty low, but I got a aligned and rotated often and after over 1 year, My tires still had about 75% thread left, no lie. All about alignment bro.
