Correct me if I'm off, but it looks like 18x10 all around works. 9.5" does not fit up front, but 9" BARELY fits up front.
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."
