The 911 Turbo is equipped with a rubber tube that runs along the underside of the front spoiler. The tube is similar to a bicycle tire. Its job is to fill up with air and extend downwards as a spoiler to switch 911’s native front-end lift with a slight down force. Due to the limitations of the tires, the maximum speed of the new 911 has been restricted to 196 mph which could have been 207 mph instead.
