Formula Drift or Formula D is the premier United States drifting series. Formula Drift , Inc. was co-founded by Jim Liaw and Ryan Sage in 2003 as a sister company to the now defunct Slipstream Global Marketing, the same partnership that introduced D1 Grand Prix to the United States. The new entity would solely own, operate and launch the first official drifting series in North America. 2014 will be Formula Drift’s eleventh year of competition. Formula Drift works closely with a huge variety of endemic and non-endemic business partners from energy drinks to the military. Most notably Formula Drift works with the largest amount of tire suppliers to a single series. Achilles, Falken, Hankook, Maxxis, Kenda, Nitto, GT Radial, and Yokohama all work together to supply teams and develop test their products.
