The Best Formula Harnesses for 2025 – Our Ultimate Line-Up
At GSM Performance, we know how important it is to have the right harness setup when it comes to open-wheel and single-seater race cars. Whether you’re building a Formula Ford, sprint racer, or prototype machine, your harness isn’t just another safety item—it’s a core part of your driving experience and track performance. For 2025, we’ve carefully selected ten of the best Formula harnesses on the market to make your choice easier.
Formula harnesses are very different from standard 6-point harnesses used in GT or saloon cars. They feature shorter shoulder straps, compact quick-release mechanisms, and lightweight adjusters—all designed to fit in confined cockpits and work seamlessly with FHR (HANS) devices. These harnesses help keep you safely locked in position, offering full upper body stability even through high-G-force corners or under heavy braking.
In this blog, we’ve broken down our top recommendations from trusted brands like Sparco, OMP, Sabelt, TRS, and Schroth. You’ll find key details on each belt’s FIA approval, adjuster material, installation type, and overall design to help you find the right fit for your car and driving style. Whether you’re chasing milliseconds in a national championship or building your first formula-style track car, this guide has you covered.
What is a Formula Harness?
A Formula racing harness is a 6-point safety belt system developed specifically for single-seater or open-wheel race cars like those used in Formula Ford, F3, F4, or prototype categories. Unlike conventional 6-point harnesses used in GT and saloon cars, Formula harnesses have:
Shorter shoulder straps, as they usually mount directly to the monocoque just behind the seat.
Pull-up lap adjusters, preferred in tight cockpits.
Ultra-compact adjusters and fittings, to reduce interference with cockpit space.
All belts are designed to work seamlessly with FHR/HANS devices.
Formula harnesses are FIA-homologated for professional motorsport and are essential in series where open-wheel vehicles are used.
