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?
*McLAREN claims an advantage with having the entire belly inclined (raked),with ground clearance increasing slightly as it proceeds aft.They offer no specifics.
*Otherwise,for a diffuser,starting where your illustration shows,the lowest drag is at 4-degrees upslope.
