Building a street-legal formula car isn't just an engineering challenge, it's a regulatory one. It took countless late nights, regulatory meetings, and a lot of thinking outside the box to make this possible.
Our cars are built and delivered as a 3-wheel autocycle and include a 4-wheel conversion kit. The 3-wheel version is already an absolutely insane machine, and it's what allows us to abide by regulations that finally make a street-legal formula cars possible. We've worked directly with the DOT and NHTSA, and want to clearly explain how the 4-wheel version works on the street.
The 4-wheel conversion kit can be installed anytime after delivery and is designed for the track to unlock full formula-car performance. It's an aftermarket part and is technically not FMVSS-compliant, which is why we can't install it pre-delivery,just like most aftermarket parts such as coilovers, exhausts, or racing harnesses.
Using the 4-wheel version on the street:
And remember; the 3-wheel version is still wild and incredibly fun. You don't have to
install the 4-wheel conversion kit if you don't want to.
Our goal was to make a true formula car street legal. It hasn't been done because it
isn't easy, but with enough research and late nights, we finally made it possible!
