ApplePayNO TRADES WILL BE CONSIDERED FOR THIS SALE:
I am selling a barely used Qubic Systems seat belt tensioner for SIM RACING. It simulates the G-Forces and seat belt pulls of a real car that adds that extra realism to your SIM RACING experience. I currently have it attached to my TRAK Racer rig and can be removed when purchased by it's new owner. I am also selling a e-Racing Labs 4 point motion system on KSL and would be willing to work out a deal if you were interested in both items. The tensioner system retails for $1,799 on most sites. I also bought an emergency stop button that connects to the system separate. I have a TRAK Racer racing harness that will be included with the tensioner system to complete the set.
See below for extra details:
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.
