The course looks dangerous,especially in town.Barricades would be nice to keep onlookers off the course.Around the trees would be good too!
You're hitting 50 kph with around Cd 0.90.If the new body cuts that in half or better,you're going to have some serious velocity and fully exposed to some serious fixed obstacles.
I'd recommend as much crumple zone as you can fit within the shell.
She looked very stable.Thanks for sharing.
