Do spoilers on commuter cars actually make any significant difference?

639 views

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!

When it comes to aftermarket spoilers, fins, and wings, the intended purposes may vary, but the practical results are the same. You see, many of these bolt-ons promise signifigant gains in a vehicle’s performance parameters that are often difficult, if even possible to measure. However, the unintended consequence of birth control is un. deniable.
