Its aluminium housing, RGB light strips and bottom, front or side mounting suit esports and professional racing enthusiasts.

Key Features

• Zero-cogging flat-wire motor delivers 25Nm peak torque and 26% higher torque density than similarly sized competitors
• Real-time true torque sensor with 0.1% sampling accuracy and a response frequency of up to 2 kHz for sharper handling
• Sustained 25Nm torque output from an industrial-grade motor, without throttling in long endurance sessions
• 21-bit magnetic encoder gives over 2 million points of precision for every steering input and surface detail
• Dual RGB light strips offer 16.7 million colours and real-time telemetry feedback for ABS, traction control, gear shifts and flags
• New force feedback algorithm paired with intelligent thermal management that runs cooler under sustained high torque
• CNC-machined aluminium housing with a rigid die-cast unibody for rigidity while keeping overall weight low
• Hands-off protection detects when your hands leave the wheel, then stops oscillation and safely centres the wheel
• Compatible with a broad range of racing and driving titles, including iRacing, F1, WRC and Forza
