Know before you buy
The Alpha Ultimate features a high-performance servo motor capable of delivering a peak torque of 23Nm, providing significant force feedback strength for demanding sim racing titles.
Yes, the integrated ball lock quick-release mechanism is compatible with steering wheels featuring standard 50mm or 70mm bolt patterns, allowing for broad compatibility beyond the Simagic ecosystem.
The base includes the motor-side quick-release, but the bottom mounting bracket is an optional add-on. You will need to ensure your rig supports bottom-mounting or purchase the specific bracket if your setup requires it.
Direct-drive technology eliminates the mechanical lag and friction found in belt-driven systems. This results in a much more responsive and detailed connection to the track, allowing you to feel subtle surface changes and weight shifts instantly.
While the 23Nm of torque is designed for serious enthusiasts seeking maximum immersion, the force feedback settings are fully adjustable. This allows you to dial back the intensity while still benefiting from the high-fidelity response of the direct-drive motor.
