Overview
A direct-drive wheelbase delivering 21Nm continuous torque for PC sim racing. Built with a 21-bit encoder and zero-cogging flat-wire motor for precise, smooth force feedback.
Performance and Precision
The industrial-grade direct drive sustains 21Nm of torque without power loss during long sessions. A 21-bit magnetic encoder captures over two million sampling points to reproduce fine road textures and load changes. An updated force feedback algorithm provides a clearer, more natural steering feel.
Motor Technology
An advanced flat-wire motor nearly eliminates detent torque for smooth, even force transmission. Support for iRacing 360 Hz telemetry ensures quick reaction to data for a more direct driving experience in competitive series.
Design and Integration
The CNC-machined aluminum housing offers durability and a modern appearance. Integrated RGB strips display 16.7 million colors animated by telemetry data. Universal mounting points allow front, side, or bottom installation in nearly any rig.
Connectivity
All essential peripherals connect directly to the wheelbase via USB. Ports support pedals, shifter, dashboard, and handbrake devices for a streamlined setup.
