Forget about the out-dated belt-drive system. Direct drive is the only known way to achieve real-life race car steering dynamic range. Its just a pure connection to the road behind the wheel. Connect your wheel directly to a fast response direct drive motor for maximized simulation of force feedback. This is the only way toward a professional sim racing. ?As our entry-level sim racing wheel base, ALPHA MINI managed to have the best range of torque for sim racing. The highest force required is usually when you hit the curbs or at the bottom of this hill. 6-8 Nm is what usual people found enough for sim racing, the remaining 2-4 Nm is used to minimize the force feedback clipping, reflect sudden change for force feedback.
