The King of Entry Level Immersion

A direct drive seat belt tensioner that increases sim racing immersion like no other device in its price range.

This innovative device transforms car simulations into an exhilarating and exceptionally authentic experience, setting a new standard for the intensity and authenticity of virtual driving.

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

Qubic System QS-BT1 Direct Drive Seat Belt Tensioner with Trak Racer Seat Harness Overview

Immersive Control with the Trak Racer QS-BT1 Seat Belt Tensioner

Powered by the same high-performance tech as the QS-220, the Trak Racer QS-BT1 is a dual-channel, direct-drive seat belt tensioning system designed to deliver physical feedback that mirrors real-world racing forces.

Whether you're integrating it with a Trak Racer motion platform or using it as a standalone device, the QS-BT1 accurately simulates G-forces during braking, cornering, wheel lock-ups, and traction loss—delivering up to 200 N of force per channel.

The QS-BT1 also performs exceptionally in flight simulation, replicating high-G load sensations during aerial manoeuvres. For supported titles, it can reproduce asymmetric engine vibrations and road surface textures like kerbs and rumble strips—adding tactile realism far beyond what wheels and pedals alone can achieve.

Key Benefits

Dual-channel direct drive tensioning with precise, responsive force
Realistic simulation of braking, traction loss, and lateral load
Compatible with both sim racing and flight sim environments
Operates independently or as part of a Trak Racer motion system
Delivers up to 200 N of force per channel for immersive realism
