Like LMB said, if you're looking for quality over style, then Dinan is a MUCH better wheel.
Too bad you're too late for the RAC wheel.
Also, you may want to shop in the "Sponsor" forum here for other options that may be better and will definitely cost less than Dinan for your other mods.
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."
