Sim-Lab is finally entering the Direct Drive Wheelbases with a huge bet. There are two main flavours to choose from: the all-mighty DDS39 and the DDS26. Both seem to have very interesting specs.
The DDS TorqueSync™ Direct-Drive Wheelbase is a no-compromise force-feedback system built on industrial motorsport technology. Developed with SOLO Motorcontrollers, it combines a 350V servo architecture, 100 kHz control loop, and patented signal processing to deliver torque response that’s faster, cleaner, and more precise than anything in sim racing.
Available in DDS26 (26 Nm) and DDS39 (39 Nm), both variants share the same uncompromising engineering and performance.

Industrial-grade motor control meets 350V power delivery.
Voltage Makes the Difference
The DDS TorqueSync™ combines a SPMSM / AC Brushless industrial motor, the same type found in industrial automation, with an internal 350 VDC bus that delivers massive voltage headroom. Hand-built with harmonised magnet pairs and distributed-wound stator cores, the motor virtually eliminates torque ripple and cogging. The high-voltage architecture provides the power to overcome back-EMF, maintaining torque at higher speeds and delivering significantly faster slew rates. The result is silky-smooth rotation with instant torque delivery that responds to rapid changes without lag or voltage sag.
Full USB connectivity designed for today’s wheels and tomorrow’s innovations.
Future-Proof Data Passthrough
The DDS TorqueSync™ features comprehensive data passthrough that works seamlessly with every steering wheel on the market. Full USB 2.0 runs directly through the base to your PC. No signal degradation, no compatibility issues, no proprietary restrictions. A dedicated 5V power line at 2,500 mA handles high-draw displays and button boxes without taxing standard USB limits. All of this flows through an industrial-grade replaceable slipring rated for 200 million cycles, ensuring reliable signal transmission for years of racing. Your wheels, your displays, your setup: connected without compromise.
Patented technology synchronizes simulator physics with motor output in real time.
Feel What Others Miss
TorqueSync™ is our patented signal translation layer that bridges the gap between simulation and servo. Running at over 100,000 updates per second, it ensures every force command from the simulator is translated to motor torque with extreme precision and minimal latency. Micro-details like tire slip, road texture, and load transitions come through cleanly, giving you authentic feedback that mirrors real-world driving dynamics.
No external brick, full power delivery built into the base.
No Brick, No Clutter
Forget bulky power bricks cluttering your rig. The DDS TorqueSync™ integrates a high-efficiency 1,500W power supply (2,500W on DDS39) directly into the housing. This eliminates cable mess, reduces failure points, and ensures the motor receives clean, stable power for consistent torque delivery. Just one mains cable, and you’re ready to race.
Universal mounting and open ecosystem. No compromises, no lock-ins.
Designed to Adapt
Precision mounting rails run along all four sides of the housing, plus dedicated front-mount points for maximum rigidity. Side-mount on a Sim-Lab rig, front-mount for a custom build, or adapt it however your setup demands. The DDS fits your rig, not the other way around.
RaceDirector™ gives you control, telemetry, and a community of setups.
Software That Thinks Like You Do
RaceDirector™ isn’t just configuration software: it’s a complete tuning ecosystem. Adjust torque curves, damping, and slew rate with precision controls that go deeper than any competitor. Telemetry FFB mode lets you see the incoming simulator signal alongside the motor’s actual output, so you can tune by data instead of guesswork. Upload your setups to share with the community or download proven profiles from the fastest drivers. Setup becomes a competitive advantage, not a mystery.
