why does it not work for me? i dont see it

yes..... you paint it invisible.....

Is there any way to remove the air intake on the top?

it's for the opt in alpha and newer only

Why the mods dpnt work ?

if you go ahead and watch the video, I show quickly the way to do it. In the opt in alpha, in the fixtures tab, there's a gear icon in the bottom left, in there you can hide the chassis permanently

Did you edit the car between Automation and BeamNG to remove the chassis? If not, how did you do this?

Yes YES YES!!! now i can do the mid70's era and their innovative designs (and big airboxes XD)

cool one, i was waiting for these kind of formula 1 cars with more aero.

mmmm yesss
