I understand the aerodynamic principles that make spoilers important for performance cars (at least in broad strokes), but I have always wondered if they actually make a big difference in cars that are not so performance oriented, especially fwd commuter cars. I know that aero is less effective at slow speeds, so I would also like to know at what speeds spoilers really give an advantage?
Thanks in advance for sharing your knowledge!

They’re cosmetic. A spoiler that operated at normal car speeds would be comically huge.
Then there’s also the fact that a spoiler would be adding downforce to the rear wheels when most cars are front wheel drive.
