I just dont understand how a tiny company like Porsche is able to offer low volume cars like the Boxster Spyder with a retuned engine, and a big company like BMW can't get their Performance seats certified in the US (or to even work with the Euro cars for that matter)? Or why they can't include the BBK in the ZCP?
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."
