I would also hate to find out that there is no benefit at all when bolting on the Mopar spoilers.
Thanks.
The problem is, you need to define "benefit" first, such as less drag, more downforce, better radiator airflow, less wind noise, etc. And as already stated , speed will drastcally change all the above factors and their benefits

I would think they won't do much at normal highway speeds but you gotta admit they look great.
Hope you find the info your looking for.
It would be interesting indeed.
? ok so get on the freeway and stick your arm out the window with your palm facing down, then then turn your palm facing forward and when the wind wraps your arm backwards tell me does the airflow matter? it does'n take much surface area to have an effect on drag or down force!

so you say that the force I feel on my hand will push around a 3000 plus lb car?

The square inches of your hand is a lot smaller than the area of a car, but at the same speed the drag per square inch would be exactly the same.

I heard the old DC spoilers for Dusters actually slowed them at the track.

I put this old American Racing aluminum unit on my 79 Magnum years ago. This was a 1 owner car....me...and from day one, she had a squirm to it on the hiway. Always felt like the back end was light. This is a GT...sway bars front and back too. (The photo shows her after we had to remove the flares due to rust damage).
Bolted on the wing, and a few tweaks to the angle of attack, and all of a sudden the car handled like a dream.
The first blast over 100 mph proved it worked....I ended up with permanent dimples in the trunk lid....lol.
I've since had to scrap my 79, but we kept all the good parts. The wing is going on my son's 78, because, guess what? It handles the same way my 79 first did.

This one really made a difference in holding down the front end. The Chally used to get very light in the front over 100mph. Added this in front and a TA spoiler in the rear and at 140, it is still very stable.

So the answer is they will work around 100 mph
Right?
They still look kool

Ever push on the rear fender of a car doing a burn out, 3,000 lbs + or -?
No traction no handling
Let me clarify:
1. The first point I think was the small amount of force your hand generates when stuck out in the windstream of a moving car.
2. my point was any moving car at the limits of adhesion takes very little force to move it, hence my example of pushing on the rear of a car during a burnout can redirect the cars angle very easily
3. And therefore a spolier that adds any downforce will help prevent a car losing control
4. And mainly, the poster who asked how could a spoiler push a 3,000lb car around, assuming the car is at its adhesion limits, requiring the need for a spoiler.
Make sense?

Which track !!!
Its a give and take thing. A spoiler might well slow you down on a straightaway but the downforce will allow you to go through the corners faster. So yeah, on a drag car you probably want to toss the spoiler but on a track car you want it there. Daily driver ... mostly there for looks!
