■ Three types of fixed-end choices:
- Fixed on the left
- Fixed on the right
- Fixed on the sub



The choice primarily depends on the driver’s personal habits and the goal of ensuring a fast, intuitive exit during an emergency.
While they offer the same level of safety when installed correctly, the following key considerations should be considered:
1. Dominant Hand:
Most drivers prefer the release buckle to stay on the side of their dominant hand for a quicker and more natural release during an emergency escape.
2. Cockpit Layout:
Ensure the buckle location is not obstructed by the gear shifter, handbrake, or other interior switches.
3. Escape Route:
Consider your most likely exit direction. Some racing regulations or vehicle types favor one side for a faster bail-out.
4. Technical Regulations:
Always check specific series rules (such as FIA) for any requirements regarding buckle orientation.

■ Proper Installation for Racing Harness
Regardless of the side you choose, safety depends on these three factors:
Snug Fit:
The lap belt must sit firmly over the upper thighs/pelvis, and shoulder straps should cross the center of the shoulders and chest.
No Twists:
Ensure all webbing is flat. Twisted straps significantly reduce the harness’s effectiveness during an impact.
Smooth Function:
The buckle must lock and release instantly. Our racing harnesses feature a quick-release mechanism designed for high-pressure environments.
