Do you plan on enclosing the wheels ?

Are you gonna round the nose in a bulbous shape?

I think it's going to be hard to sand a smooth surface over the two different type of foam.
But I've been wrong before. Once. |

what do you think
If you're pleased,them I'm pleased.Anything you do is an aerodynamic improvement.
I would add,however,that the undercut nose produces the highest possible positive lift.At the velocities you'll be racing at it may not be a problem,but technically speaking,it's the worst choice.

I think it's a safety feature. The lift will be proportional to the area facing downward, so the bevels on the side help.
The area can be reduced further if the front edge is pulled back by rounding the nose down. A little duckbill diverter would help.

true 
it's the worst in drag or in lift?
i wan't a neutral car with 0 lift, because if i have a lot of lift i will have less grip, and if i have a lot of downforce i will have more rolling resistance.
what do you think? i need more downforce than lift? and it's even important? because my top speed is of 75 km/h
thank you. |

Somewhere between #3 and #4 indicates a neutral condition.

That would depend on the angle, more upright and bluff will have less lift.
I think you were on the right track back in Permalink #131
To address the high stagnation point (the point where air can't decide to go up or down) add a crushable chin spoiler.
