Realistic G-Force & Braking Feedback

Experience the full weight of real-world forces as the QS-BT1 dynamically tightens the seatbelt during heavy braking and high-G cornering. Dual voltage channels deliver precise, real-time force as you hold a racing line, countersteer mid-drift, or swing through fast turns. The system adjusts belt pressure to mirror deceleration loads, lateral overloads, and centrifugal force—giving your body intuitive cues for braking points, apex pressure, and vehicle control.

Detailed Vehicle Dynamics & Surface Effects

Feel deep engine pulses, kerb strikes, and shifting road textures transmitted directly through your harness. The QS-BT1 accurately reproduces surface changes and power delivery across supported titles, adding the subtle tactile detail that brings simulation environments to life. Each gear change triggers a responsive belt tug, simulating the shift jolt found in high-performance vehicles for added realism and immersion.

Multi-Axis Flight & Advanced Simulation Feedback

The QS-BT1 supports G-force simulation across both vertical and lateral axes, making it ideal for racing and flight. It can replicate positive and negative Gs, throttle transitions, weapon recoil, and even flare deployment with precision. While motion platforms excel at short-burst effects, they struggle with sustained Gs—something even high-end 6DOF rigs can’t fully reproduce. The QS-BT1’s 200 N channelled system fills that gap, delivering the prolonged physical load your body expects.

Trust & Safety

  • Designed with voltage protection and speed-limiting logic
  • Force output tuned for immersion and user safety
  • Compatible with integrated Motion-Lock circuits (QS-DD-20, QS-220, QS-V20)
  • Optional external Motion-Lock switch supported with accessory

Universal Bracket for Trak Racer Rigs

The precision-engineered, powder-coated aluminium bracket provides a secure, rock-solid mounting solution for TR40S, TR80S, TRX, and TR8 simulators, ensuring every force is accurately transmitted.

Everything fit perfectly. The parts were mounted on the Track Racer TR8 Pro frame. The only thing that could be changed is the Allen screws between the bracket and the belt tensioner. Maybe they should have been hex to make it easier to adjust the height. The Allen key is too big.

GAME CHANGER

Easy to install with the Trak racer adapter, the results for what you see on your monitors during a race and feel with the tensioners is a true racing simulator upgrade, highly recommend to anyone wanting to really wanting to feel the G forces on a track or the bumps and immersion at its best, thank you again Trak Racer for the fast delivery, only suggestion would like to make is the option to buy the emergency shutoff switch / motion lock - mapped the pause mode to my steering wheel to be able and freeze the tensioners, and I had to modify my 4 point Trak racer harness to a 5 point harness, waist belt does rise up with the tensioners. Still a great buy!!
