What is new in the ST6
The most obvious change is the shape. The ST6 profile projects further forward than the ST5, which gives open wheel drivers more downward vision and helps the aerodynamics. The range now comes in three shell sizes, including a new extra small shell, so the helmet suits the head better instead of relying on padding to make up the difference.
The composite helmets are lighter: Stilo quote up to 11% less weight than the ST5 composite equivalents, and up to 10% on the carbon models. Inside, the cheek padding has been redesigned for a closer, more stable fit, with thicker or thinner pads available separately, and the ventilation has six chin bar vents plus crown vents. The injection moulded visor has a new washable anti-fog treatment and new hardware, and its locking system meets both FIA 8860-2018 and FIA 8859-2024.
What the model names mean
| Model | What it is for | Approval |
|---|---|---|
| ST6 FN | Open cars, no electronics or side ports | FIA 8859-2024, Snell SA2020 |
| ST6 GT | Closed cars, with built in radio connection | FIA 8859-2024, Snell SA2020 |
| ST6 GTN | Closed cars, no electronics or side ports | FIA 8859-2024, or 8860-2018 on the 8860 version |
| ST6 Rally | Rallying, with built in intercom and earmuffs | FIA 8859-2024, Snell SA2020 |
| ABP versions | Open cars, extra forehead protection | FIA 8859-2024 ABP, or 8860-2018 on the 8860 ABP version |
Most models come in composite and carbon, and there are 8860 versions homologated to FIA 8860-2018, the standard asked for at the top of the sport. The ST6 FN ABP is billed as the first helmet to meet the FIA 8859-2024 ABP homologation, which adds tougher testing on the forehead area to protect open cockpit drivers from flying debris.
Which ST6 suits which driver
For single seaters and open sports cars, the FN is the starting point: the composite version for club racing, carbon to save weight, and ABP if your regulations ask for it or you want the extra forehead protection. For saloons and GT cars, choose the GT if you run a radio, and the GTN if you do not.
Rally crews get the ST6 Rally, a full face helmet with an intercom built in, including a dynamic noise cancelling microphone and noise reducing earmuffs. The composite version comes in a titanium finish.
Garreth's advice is to check what your championship asks for before looking at shells or colours: an 8859-2024 helmet covers most club and national racing, while some series specify 8860.
