How to reduce aerodynamic drag of a vehicle.

Is there a simple way to lower aerodynamic drag on a vehicle? Downloaded a mod and for whatever reason the car has a LOT of drag and I just want to lower it to a more appropriate level.

 

I think the drag applies do each triangle, so not simple. https://documentation.beamng.com/modding/vehicle/sections/triangles/

But maybe you can use "scaledragCoef" for overall changes
