ST6 F helmet and comms package
We can build the whole package for circuit racing: an ST6 F Composite or Carbon, the matching headset or earpiece, the right adapter cable for your car's radio or intercom, and setup advice from our radio engineer. Tell us your helmet size, connector type and system, and we'll confirm the package and price before you order.
ST6 F connector options
- EarMuff / Speakers: passive noise isolation, for noisy circuit cockpits
- 3.5mm Mono: the most widely used in NZ, AU and the USA
- Stilo Earbud Connector: Stilo proprietary, for Stilo earbuds
- RCA Connector: the European race team standard
Questions we get
What is the difference between ST6 F and ST6 FN?
The F comes with Stilo electronics and a comms port built in. The FN has no electronics and no side ports, so it's lighter and cleaner, and you can add comms later if you need them.
What is the difference between ST6 F and ST6 GT?
The visor is the main thing to compare. The GT has a short sun visor for mixed light and daytime endurance. The F Composite has a standard clear visor. Check the listing for other F models.
Do I need ABP for open wheel?
It depends on your category. ABP adds an extended forehead zone for debris protection, which is why formula categories ask for it. Check your rulebook, then look at the ABP models above.
Carbon or composite?
Carbon is lighter: the ST6 F Carbon starts from about 1,230 g against about 1,420 g for the F Composite, in the small shell. That matters most on long stints. Composite costs less and carries the same listed standard on those two models.
Do you ship to Australia?
Yes. We ship to Australia by tracked courier from New Zealand.
