Well, This year the rules had changed and it's compulsory having a bottom,belly on the car to prevent driver feet or legs to touch the ground.

So, i have to build a " flat bottom" before august 16 to be able to compete.
My question is, it's possible to build a bottom for the car that also improves the aerodynamics?

any tips?

this is going to be like another little subproject, like the nose and the suspension.

thank you!

edit:

i have designed that so far, it's ok? the diffuser has to be 5 degrees for optimum drag?
