Yes, kind of. It's not called that, but just an application of basic dynamics models. Mostly can ignore aero for larger stones. If you really want to be precise you'd first have to do the aero model and then make alterations to the dynamics model based on expected airflow. With mud or liquid then your aero changes and you have to iterate...

But some things are just easier with common sense and testing.

Oh this line of shit again. Materials stick and get flung off at all angles as they come loose.
So,
Does any other manufacturer call it a stone guard, or just Toyota?
I agree with the two engineer theory. I think something got screwed up in the translation. Maybe the Japanese word for air or aero sounds like stone.

Subaru calls it a splash guard. BMW calls it a wind deflector.

I went back on the internet to find out definitively what these things are called. And I've come to the conclusion that nobody knows. There are at least five different names for them. How can these things be on virtually every vehicle and nobody knows what they are? It's incredible.
Maybe they were developed by AI.
We're all doomed.

On the 2020 WRX the equivalent part is called "Spoiler. Air Flap." or "Plate Air Flap" depending on which page you are looking at.

However, Toyota does seem to want to call them mud guards, splash guards or just Plate for other cars, notably the Corolla.

This is what happens when I can't sleep...

Can we now conclude that it was a 'stupid question'?

This is getting really funny.
Splash shield. That's a good one. Gotta make sure I shield my tire from splashes! I don't know if the car could survive without the splash shield.

I call it the rubber thing in front of the rear tire. I noticed a couple months ago the one on the passenger side was missing the clip on the bottom. I went to Toyota and got a couple.

Are you really this obtuse all of a sudden or just siding with the alleged "engineer" because he is saying what you want to hear?

When the wheel rotates mud, sand, and stones can stick to it. As you pick up speed the centrifugal force will eventually overcome the adhesion and they will fling off. They can do that at any point in the rotation. A surprising amount will fly forward and down with some serious velocity. The corner of the rocker below the front of the wheel well liner is ungiving metal. If nothing protects it then it will eventually (some times rapidly depending on where you live) get blast like a sand blaster. This leads to rust and structural damage. The rubber or plastic can absorb the impacts without degrading as quickly as solid steel protecting your rocker corner. You are not fucking protecting the wheel from splashes you are protecting the rocker from the wheel. In most of the real world this is a very important feature but I get that Californians and Hawaiians are confused by such things.


You saw the fucking picture I posted of mine do you think I packed crap in there on purpose? Do you think almost every manufacturer that calls it a shield or guard had a translation issue? For that matter do you truly think that the top automotive manufacturer in the world farms out their tech writing to some almost illiterate translator? Are you really that gullible?

Yes the little rubber flap will have a slight aero effect but that is not the only or even main purpose.

I swear people on here are getting fucking stupider every day.

It is basic physics. I thought engineers understood such but guess I was wrong.
