I'm thinking this is Spike Racing on Instagram because I think he has chassis #4 of 7, but not 100% sure. I've messaged with him a few times and he sent some cool footage of the car and even video of the engine being dynoed after the refresh. He took the car to Laguna Seca for the historics in 2019.
