Think you need a big budget and a lot of time to do aero testing on your car? This guy did it with a 3D printer and some home-brew engineering.
If you haven’t already stumbled on the SuperFastMatt YouTube channel, I highly recommend you go and look it up. Matt has been building and racing a land speed car along with other projects like a lifted Dodge Viper and has documented the entire process along the way.
