Thanks a lot Brian!Next time please warn us that oncoming cars may be an issue!
We take things very literally here!

Seriously, I'd love to see a test in a wind tunnel for some of these bodies.

Let's shrink this down even further and discuss golf balls. The dimple patterns and number of dimples affect how the ball flies, so an RC car body that is 50 times larger definitely will affect how the air is moved around it.
Nice arm. I told you to loosen the grip on that controller.

All joking aside, I got that from when I slapped Soviet, but he has such a hard head that it broke my arm

So if they make no difference to you then your car is too slow to exploit the differences.
You don't have to shrink air, air is a constant force, and the bodies we run make downforce in varying degrees, Some one needs a wind tunnel to prove the naysayers that these things really do make a difference. At 10 MPH it's not a whole lot, so if your cars that slow it won't make a difference, but at 35 mph your TC's punching a bigger hole in the air than you realize, and that air has to flow around the body.
You don't care because you can't tell the difference, and therefore you think you're right.

Less than 10% total car handling....I'd bet my life.

i wish i can test my car's aerodynamics in a wind tunel
that way i can REALLY get into exact down forces and air flows of my car
