World Time Attack is genuinely insane.
We’ve already shared with you the certified bonkers stuff we spotted around the paddock on Friday, but here’s a list of the engin’-swappin-est sideways-slidin’-est top-speed-blastin’-est winners from the Saturday.
If you’re not all over it - World Time Attack was founded in 2008 and is based on the time attack scene in Japan. The original concept was to bring the best tuners and cars from Japan, Australia the US and the world to compete in a single lap challenge.
The appeal of such an event is that, unlike FIA-regulated race disciplines, it is relatively cheap to run a car in the time attack challenge. Plus, with a more flexible set of regulations and the requirement to complete just one lap, it can be much more exciting to see the kinds of wild aero and hand-grenade builds concocted by the teams.
Since its initial success, it’s expanded out to many categories – There are four time attack classes, one sprint class and a drift class.
Pro Class

In Pro Class, drivers participate by invite only. The cars run control tyres, but are otherwise completely wild. This where the World Time Attack time is earned.
This year’s winner (and new lap record holder) – Tim Slade in the MCA Suspension Nissan S13 (1:20.9710)
Pro Am Class

The same as above, but allows for non-pro drivers.
This year’s winner – Robert Nguyen in the 101 Motorsport Honda CRX (1:26.2760)
Open Class

The same as above, more restrictions on the allowed vehicles
This year’s winner – Adam Casmiri in the JDM Yard / Hardrace Honda Civic (1:27.5620)
Clubsprint Class

Entry level time attack, same as above, a list of ‘supercars’ are banned, Pro drivers are not allowed.
This year’s winner – Jordan Cox in the Team Raptor / IS Motor Racing Mitsubishi Evo IX (1:36.8390)
The Flying 500

14 cars, 3 runs, 500-meter race with a rolling start, highest top speed wins.
This year’s winner – Aaron McGranahan in the Precision Automotive Racing Nissan R35 GT-R (269kp/h)
Drift Challenge

Turn 16, 17 and 18 plus a run-off and run-up area are the only parts of the track in this event. Competitors are judged on their line, angle, speed and ‘overall impact’. Points are deducted for excessive use of handbrake, spins and straightens. Going off-track or hitting a cone results in a score of zero.
This year’s winner – Beau Yates in the Toyota Genuine Parts 86. (although some would argue a 2JZ isn't an 86 genuine part...)
