After setting a base lap of 9:21.8 the guys behind the project figured they'd have a fair bit of work. Turns out a new set of Kumho V70A semi-slick, road-legal race tires paired with Gabriel Pirana's driving is all they needed. With just that mod Pirana set a lap time of 8:59.9, and that was while having to deal with one spot of slow traffic that was getting around a stricken car. According to Wikipedia, this puts them between a 2010 Range Rover Sport Supercharged and a 2007 Chevrolet Cobalt SS.
Even though the team achieved its goal on its first attempt, the Ringbanana game isn't over – there's probably a suspension mod in the near future while the guys figure out just how quickly they can go. The video above does a good job of showing just how fun it can be driving a slow car fast.
