Another Ford GT, this time 279.9 mph. (280.1 at Arkansas). Despite the claim of no body mods, there's a 1 1/2" or so spoiler added to the rear, perhaps to direct air flow over the braking chute. The Ford GT body is based on a Lemans race car (Ford GT40), and is less prone to speed related issues (lifting of rear end or lifting of front end and blowover). My impression is that the 350Z body style is going to produce lift at high speed without some modifications. If there's enough excess power such as the drag cars, the entire body can be pitched nose down to produce downforce.
