Force feedback (FFB)
Force feedback (FFB) is the motorised resistance and vibration a sim racing wheel produces to convey grip, kerbs and weight transfer — the main way a driver 'feels' the car.
Force feedback — definition
Force feedback (FFB) is the motorised resistance and vibration a sim racing wheel produces. It is how the simulator communicates what the car is doing — the loading of the front tyres in a corner, the rumble of a kerb, the moment grip breaks into a slide — so the driver can react by feel rather than by sight alone.
Entry wheels such as Logitech G's G29/G920 use gear-driven FFB, while serious rigs use direct-drive wheelbases for stronger, more detailed feel. Good FFB is what separates a realistic simulator from an arcade racer.
