Force feedback wheels are built to send haptic information from what’s happening in the sim into your wheel. This is what makes sim racing feel like you're actually driving a car. Ideally you want the force feedback to be as quick and smooth as possible so that there's no lag between what you see and what you feel. Not only does this feel more realistic, but it also allows you to react more accurately, ultimately improving your performance. There are three main ways that force feedback is generated in sim racing wheels: gears, belt and direct drive. Each of these technologies provides a different level of power and smoothness - and the more power and smoothness you get, the higher the price.
