Why do some sports cars have moving spoilers?

Question

So when you play games (say Forza Horizon) and you see the more high end sports cars have spoilers that move up and down when it comes to high speeds and breaking instead of being static. Why do some cars do this? What’s the benefit to the engineering behind it?

Answer 1

It allows the car to go faster in a straight line by reducing drag when the downforce isn’t needed, enables the computer to control the car’s balance on the fly, and acts as an airbrake to make the car stop more quickly.
