Force feedback (FFB)

Sim Racing

The motor-driven resistance and detail a wheelbase sends back through the wheel — the forces that let you feel kerbs, grip loss and weight transfer through the rim. Peak strength is quoted in newton-metres (Nm), but the headline number isn't the whole story: how cleanly and quickly the base reproduces small details often matters as much as raw torque, and most drivers run well below the maximum. Concrete example: a 8 Nm base set to a comfortable strength can feel more informative than a 15 Nm base cranked to a level you have to fight. Buying impact: treat peak Nm as a ceiling, then judge bases on smoothness, fidelity and software tuning rather than the spec sheet alone.
