I am 6â€™2â€³ tall and my son is only 5â€². Can Trak Racer products be adjusted to suit both of us?

Trak Racer adds adjustable components to accommodate users of all sizes!

Why do Trak Racer products appear to be a little more expensive than other simulator products?

We render many extras that competitors simply donâ€™t with their rigs. Thoroughly compare what we provide with that from one of our competitors? We believe we offer the best value high-end gaming rigs out there!

Do Trak Racer products require assembly?

Trak Racer products are shipped out partially assembled to reduce shipping costs. Depending on the rig, assembly can be as quick as 30 minutes, through to many hours. See the relevant product page for details. PS, this doesnâ€™t render the lifetime of tweaking and optimising that our customers love...

Are Trak Racer products comfortable?

All Trak Racer products are designed, developed, tested, improved, redesigned and manufactured. If the seat needs extra padding we add it, if the controls need to be closer, further away or adjusted, we do it. The result is a setup that is strong enough to accommodate the most demanding racers and will help you to remain focused and comfortable for hours!

Are Trak Racer products compatible with PS5 and XBox Series X and S?

You bet, we have lots of new products we are bringing to market and coming your wayâ€¦ Stay tuned!

Are Trak Racer products compatible with PS5 and XBox Series X and S?

Trak Racer products are universal. They work with PS5, PS4, PS3, PS2, Xbox and PC systems.

Where are Trak Racer products made?

All Trak Racer products have been designed and engineered in Australia and shared with our manufacturing partners across the world.

Are Trak Racer products easy to store?

Not really, but why would you want to hide such a beautiful piece of furniture? If you really need to you can dismantle a couple of our rigs in several minutes to minimise the size. We do have the FS3 which you can easily store way!

Iâ€™ve arranged someone to build my rig and Iâ€™m not happy? Will Trak Racer reimburse me?

No, Trak Racer will under no circumstance cover costs associated with installation or any labor from an installer not recommended or approved by Trak Racer.

Immersive Racing Forces
Mounted with Precision

Experience 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.

KEY FEATURES

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

Universal Bracket for Trak Racer Rigs

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.
