It's common sense that anytime you do anything with the suspension you need to go get an alignment afterwards. That way the camber won't be THAT far off. 100 bucks for a camber kit that you can install yourself and an alignment is less expensive than a pair of high performance tires after just 1000 miles. Or even just rotating your wheels front to back would have saved the tires a little longer, since the front wheels suffer the most from the camber.
