You'll be fine since you'll be doing some hard driving. You may want even more negative camber.
And toe does eat up your tires more than camber, but it's just something to check. Over time the inside edge will wear faster than the outside edge. I was running on the cords on the E36 M3 and didn't know it because the outside edge looked fine.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
