<p>The Dodge Viper is about to be killed off, but that doesn't mean it's going away quietly. The Viper ACR just recently <a href="http://www.roadandtrack.com/new-cars/news/a27254/the-dodge-viper-is-going-out-on-a-high-note-setting-13-track-records/" target="_blank">set a record at 13 different race tracks</a>. There's a multitude of factors that go into making a car that fast around the track, but one of them is the downforce created by one of the largest wings you can buy on a factory car.</p>
