Just a warning to RAC owners. These don't fit. The thread is 12mm but the shank is 14mm.
They work great on the stock wheels and fit the APEX wheel too.
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."
