Well if it's Habberstad I wouldn't be surprised....he likes to charge full retail on everything.
That brings up an interesting issue: the carbon front pieces and the rear spoiler have to be super easy to install....why not do it yourself? I've also heard the pedals are somewhat easy if you have a good electric drill. I'm not normally the kind of guy that would so these projects but these seem like simple installs.
Because i'm getting Jet Black I will pass on the carbon fiber lips...I don't think you'll notice them. The spoiler looks great on black in the pics I've seen in this forum.
