The Yokohama World Time Attack Challenge (WTAC) 2011 was a massive success for the promoters, competitors, fans, sponsors, and vendors alike. Ian, Nathan, Kyle, the announcers, and the volunteers who all make up the World Time Attack Challenge and Superlap Australia successfully put on the best damn Time Attack event anywhere in the world to date.
If you missed WTAC 2011, you should make a vacation out of it and attend WTAC 2012. The world's fastest time attack cars, a huge vendor row, show cars, crazy drift cars without I don't know how to build an import Chevy LS engines, smoking hot Australian models (wait until you hear them speak with that accent), and a bunch of cool enthusiasts all in one place means you really need to go. Screw the Tokyo Auto Salon unless you've got that otaku style yellow fever. Make your 2012 vacation a trip to WTAC 2012. There are plenty of Asian chicks in Sydney anyway so you'll be fine.
