Here's the Hot Wheels Double Loop Dare Stunt from X Games
3 July 2012 - Autoblog
Team Hot Wheels drivers Tanner Foust and Greg Tracy suited up and executed the Double Loop Dare stunt at the X Games.
The pair went through the 20-m-tall loops, which replicate a similar Hot Wheels toy track set, hitting 84 km per hour and pulling 7Gs in the process. Nifty.
The successful stunt gets marked down as a Guinness World Record, next to other amazing feats like the World's Largest Collection of Rubber Ducks.
