Or does it only help cosmetically(opinion-based) alone?

Since the pic shows an AutoX course... I'd say that the spoiler has zero affect at the speeds you could achive on an AutoX course, and minmal (if any) affect at higher speeds. It is too low and too small to generate noticable downforce. But that's just my opinion.

It's cosmetic.
Or there's the old line...it produces downforce equivalent to it's weight :D

You must have missed the huge picture above my sig.

Well then in a parking lot I'd venture to say it's not generating any downforce...

:lol:

But really... it's probably not generating much if any appreciable downforce at any speed...

Don't know about BMW sedan aero, but on a Porsche the spoiler is exactly that, a spoiler. It disrupts the airflow off of the roof to reduce the lift in the back, which is not quite the same as adding downforce. The net effect is the same, though.

Bro

With a wicker bill or some attatchment of that sort it may aid in reducing form/pressure drag at higher speeds, but it is mounted too low and close to the trunk lid for somthing of that shape to make any significant downforce.

It will produce some downforce (not anything noticeable), but very inefficiently.

pretty car

Static downforce. :rofl

For autox down force will not be obtained by wings. More by weight transfering.

Just a question, how fast to you go in autox? Now when do wings start helping.... If I am thinking the right numbers they are pretty far apart.

As said above, it probably reduces some lift. No downforce.

A properly designed setup can generate a good amount of downforce even at low speeds, albeit probably with a lot of drag once speeds get higher. Not really practical tho.

Yea, to be effective you'll need an AM style mutli element huge ass wing setup like Sias is now running. Look at the big aero Fsae cars and you'll see some really nice stuff. generating extreme downforce very efficiently at very low speeds.

:dunno :confused

You just wanted to post a pic of your car didn't you?

Or, you could use leading or trailing edge blowing ;) CCW FTW.

Technically speaking, a spoiler reduces drag and a wing produces lift (either positive or negative). Although spoilers might not create much (if any) downforce, they can have a stabilizing effect on the rear of the car at high speeds by reducing the high-velocity turbulence off the car's trailing edge.

6 = 12/2

It's the same thing. If it's reducing lift, that means it's creating downforce. I think what you mean is that whatever downforce created is not enough to cancel out the lift created by the car's shape.
