I've only ever made one livery for that particular car, I used superbike photos for inspiration and reference, Seems to be much more fitting, I may have another shot at it though as I agree its a hard car to work on.
I decided to do this. I started with matte black and filled in the rest. I wanted to make it look like the panel is one of those covers for the passenger seat for better aerodynamics but there isn't a passenger seat to begin with lol
