Sim-Lab showcased its first two direct-drive wheelbases at the SimRacing Expo in October 2025. The Dutch manufacturer is now taking the next step: its DDS26 and DDS39 TorqueSync models have been available for pre-order since August 1, priced at 1,499 and 1,999 euros, respectively. For a brand best known for its aluminum-profile chassis, pedal sets, and steering wheels, this is a real shift in focus, and it’s been a long time coming.

DDS26 or DDS39: What Really Sets Them Apart

The main difference lies in torque: 26 Nm for the former, 39 Nm for the latter. The DDS26 weighs 11.1 kg and houses a 1,500 W peak-rated power supply, while the DDS39 weighs 13.5 kg and houses a 2,500 W one. Sim-Lab positions the DDS26 as its core model, with torque that, according to the brand, covers both GT and single-seater applications, while the DDS39 is designed for those who want extra headroom. Note that Sim-Lab also refers to them as DD26 and DD39 on some pages of its website; these are the same models.

Otherwise, both models share the same technical foundation: an internal 350 VDC bus (25 A on the DDS26, 40 A on the DDS39), while virtually all high-end models operate at 48 V, a DSP control loop clocked at over 100 kHz, which Sim-Lab calls TorqueSync and claims is patented, a 24-bit encoder with 16.7 million steps per revolution, a USB 3.0 connection, and a 48-month warranty. A detail that matters on an already cluttered desk: the power supply is built into the case, so there’s no external power brick to find space for, just a 110/240 VAC power cord.

Sim-Lab did not embark on this transition alone. The technical aspects were entrusted to SOLO Motorcontrollers, an Italian specialist in motor control, while the Dutch brand retained responsibility for the specifications, the passthrough, and the quick-release mechanism. The wheelbases are manufactured in Italy.

The key selling point Sim-Lab emphasizes most is consistency. Whereas many other wheelbases reduce their torque when they heat up, the DDS26 and DDS39 maintain their full power output for as long as you’re driving. That’s thanks to the active cooling system built into both units, and it’s exactly what you want in endurance racing.

A Founders Edition for early buyers

Both models mark the launch of a Founders Edition. Each unit is individually numbered, features a special engraving, and comes with the new Xero-Play V2 quick release and a collector’s booklet. This isn’t just a cosmetic detail: the official specifications state that the listed prices do not include the quick-release mechanism, and the Founders Edition is the version that does include it.

Sim-Lab also emphasizes openness. The passthrough delivers 2,500 mA at 5 V to the steering wheel, compared to 500 mA on a standard USB port, which is enough to power a steering wheel packed with screens and LEDs. The brand claims compatibility with most USB steering wheels on the market, with no requirement to stick with its own products. Its proprietary software, RaceDirector, manages torque, filters, slew rate, and profiles, with real-time force feedback telemetry to fine-tune settings.

How does the pre-order process work?

The listed prices of 1,499 and 1,999 euros include 21% Dutch VAT; the final amount is then adjusted based on the country of delivery. Reservations are made with a refundable deposit, and Sim-Lab publishes regular updates on production progress.

The wheelbases ship from the brand’s European distribution hub via tracked shipping. Bundles including the brand’s own chassis and accessories will be available at a later date; for now, the DDS26 and DDS39 are available for purchase on their own.
