REAL-WORLD USE / EXPERIENCE

In use, the extension creates a more natural driving position, especially for rigs where the wheelbase sits too far forward. The added distance helps reduce strain on arms and shoulders while improving leverage and control. Despite the extension, the hub remains solid under load, preserving the detail and strength of force feedback from direct drive systems. The GSI AH100 hub 100mm wheelbase extension hub allows for precise positioning without sacrificing performance.
