I had vibration with the fronts and called them. I did the break in as instructed but they felt it was still pad deposits. They arranged for AutoTalent to install new rotors for me.
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."
