WRT to the camber plates, I believe it's supposed to help even out your tire wear, especially if you drive aggressively. Are your front tires noticeably wearing more on the outer edges now? If so, then the camber plates will probably do you good, especially in combination w/the strut brace. I don't have experience with either, but this is what I've read. It'll sure be interesting to hear from the folks who do have them though!
