Just how much carbon fiber would you like on the MP4-12C? In McLaren‘s new configurator, which went online this week, you can outfit everything from the splitters to the engine panels to the interior with the lightweight and strong composite. The deeply customizable Web site offers 17 exterior colors, wheels and tires for street and track duties, and a surprising amount of interior options. We went with a McLaren orange and carbon fiber motif with dark grey, superlight wheels shod in race-ready rubber. Forget the non-essentials like luggage sets and floor mats. We opted for lightweight, and the Stealth Pack, which darkens the exhaust pipes and wing supports, because it looks cool. Gordon Murray would be proud, even though he isn’t. On the site, you can also view the pre-configured cars of vehicle designer Frank Stephenson, McLaren boss Ron Dennis, and British F1 champions Lewis Hamilton and Jenson Button.
