WHAT'S INCLUDED
BRACKET COMPATIBILITY
QS1-BU-BRACKET-CA
Regular price Sale price $2,849.00 CADExperience every braking, cornering, and gear-shift force like it’s real. The QS-BT1 dual-channel direct-drive seatbelt tensioner delivers up to 400 N of responsive force, enhancing your simulator with lifelike G-loads, engine vibrations, and road textures. Mounted on a precision-engineered bracket, it stays rock-solid, ensuring every force is felt exactly as intended.
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.
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.
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.
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.
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!!
