The team made it thanks to support from GoFundMe donors, and sponsorship from Kumho Tires and Prefix, a design and prototype company based in Michigan. They're using two Viper ACR GTS-R commemorative-edition cars, which are appropriate for competing track cars since they have the same white-with-blue-stripes color scheme as Dodge's old Viper GTS-R racecars. The cars are supplied from ViperExchange and BJ Motors and equipped with Kumho Ecsta V720 tires.
According to the group's Facebook page, the team has been practicing since Wednesday, July 19. A video posted today highlighted that the only mechanical issue so far has been an overheating problem that was solved with a new thermostat. Each car is running a different suspension setup for practice - one soft, the other hard - and they'll adjust them as needed. The plan is that both cars will use the same setup on the record attempt. To claim the record without any argument will require beating the 6:45.9 time set by the Nio EP9 electric car. Right behind it is the Radical SR8LM, which is technically street-legal, but not really a street car. It set a time of 6:48. As for true street cars with gasoline engines, the target the Viper team will really want to beat is the Lamborghini Huracan Performante, which pulled off a time of 6:52.
