Trustpilot

QS-BT1 is a multi-purpose, dual channel, direct drive seat belt tensioner that increases sim racing immersion like no other device in its class and price range.

It can improve the overall experience offered by QS motion platforms, or used as a standalone device.

Simulation of:

  • braking
  • lateral accelerations
  • centrifugal force in high speed cornering
  • wheel spin and wheel locks
  • traction loss
  • engine vibrations
  • vertical G-force
  • road surface effects like rumble strips are also available for games that support them

Designed mainly for sim racing application, with its 200 N of force per channel it is also possible to use it in flight simulators -so you can feel the forces during high G maneuvers.
