Compare Stilo ST6 helmets and accessories for circuit racing, rally and karting in New Zealand and Australia. ST6 models differ in shell, communications provision and certification. Check the actual label and configuration of the individual helmet against current category and event rules before use. Harris Race Radios™ supplies Stilo products and can advise on helmet communications; we do not claim a direct Stilo supply-chain relationship.

ST6 FAQs
What is the difference between ST6 FN and ST6 GT?
They are different helmet configurations. Compare the exact product's FIA label, shell, fit and communications provision with your series regulations; a model name alone does not establish eligibility.
What is the difference between ST6 F and ST6 FN?
Communications provision differs by model and configuration. Check the product specification and connector before selecting a radio or intercom kit. Harris Race Radios™ can help compare options.
Do I need ABP for open-wheel racing?
ABP requirements depend on the current category and event rules. Check the helmet's physical label and confirm the required standard with your organiser rather than assuming all formula categories have one rule.
Carbon or composite ST6?
Compare shell construction, fit, weight and the specific model's certification. See our ST6 Composite vs Carbon comparison.
Can Harris Race Radios™ help with ST6 communications?
Yes. Ask us to check your exact helmet model and the radio or intercom connector before choosing a compatible wiring solution. Rex's official radio-certifier authority is separate from helmet homologation.
