Trak Racer universal Qubic QS-BT1 seatbelt tensioner mount

The Universal Qubic QS-BT1 Bracket is a custom, heavy-duty mount designed to seamlessly integrate the revolutionary Qubic QS-BT1 seat belt tensioner into your sim racing cockpit. With this bracket, you attach the dual-channel direct drive system directly behind your racing seat, so braking forces, G-forces, bumps, and traction loss are realistically transmitted as physical pull on your safety belt and onto your body.

Robust construction for strong G-forces

Since the Qubic QS-BT1 seat belt tensioner works with an impressive combined pulling force of up to 400 Newtons (approx. 41 kg), an absolutely torsion-resistant mounting is crucial. The bracket is made from 3 mm thick, powder-coated aluminum. This guarantees an extremely firm and secure connection that transmits the force feedback of the seat belt tensioner to you without any loss, without the material giving way or flexing.

Maximum compatibility for Trak Racer and other brands

This bracket is an essential upgrade for all tube frame chassis or rigs that don’t offer direct Qubic compatibility "out of the box."

You definitely need this bracket if:

• You own a tube frame rig with adjustable seat consoles or seat rails (e.g., Trak Racer TRX, TR8).

• You have an aluminum profile rig with a 40mm profile on the back (e.g., Trak Racer TR40S).

• The back of your rig does not have at least two T-slot rails spaced 40 mm apart.

You do not need this bracket if you own a Trak Racer TR80S, TR120S, or TR160, as these already have sufficient aluminum profiles on the back for the standard Qubic mounts.
