    Hey man. It’s all aero. Planks sanded down to thin wedge are nice and aerodynamic. Watch the league races. Other than the Street Rod and Door Slammer classes (1/24-25 scale bodies) all of the pro cars are thin wedge/planks. There’s just no reason to do it any other way if you are going for speed.

    No more callers please we already have a winner. And that my friend confirms my theory !! Now it's on the the question of how the air reacts under the car and is there anything that's been experimented with in that regard ?

    Some of the top unlimited cars are 3D printed plastic.

    A lot are getting that way actually. I am just saying that the thin wedge/plank shape is most common. The 3D printed cars have the thin wedge shape as well.
    Gotta admit, if I had a 3D printer there would be a lot less dust in the basement. :cool:
