Stilo ST5 FN Carbon FIA8860-2018 Helmet
The Stilo ST5 FN Carbon FIA8860-2018 Helmet boasts an autoclaved medium tensile carbon construction, resulting in a remarkably lightweight and highly protective design. Ideal for open-cockpit racing, this helmet exceeds the latest FIA 8860-2018 safety standards while offering unparalleled performance in terms of weight and aerodynamics. To reduce weight, electronic and side ports have been omitted, but this helmet is compatible with side and frontal drinking systems. Additionally, it features eight ventilation holes that can be integrated with Stilo Helmets Top Air systems. The earmuffs are designed to provide superior noise isolation and are certified for track use, with the added convenience of adjustable pressure and removable options.

Stilo's ST5 FN series of helmets eliminates the integrated accessory ports that are commonly seen on Stilo helmets. Removing these ports, and combining with a full Carbon shell, results in one of the lightest and most aerodynamic full-face helmets on the market. The taller eyeport is ideal for use in both closed and open cockpit racers. Two shell sizes - one for X-Small through Medium, and another for the larger sizes - allows for weight savings without sacrificing fit. The standard 3mm Clear visor (other shield types in a variety of tints sold separately) mounts with machined aluminum fasteners and creates an air-tight seal via a rubber seal.
Under the new FIA 8860-2018 standard all helmets must withstand the following tests:
Standard impact: Helmet impact at 9.5m/s. Peak deceleration on ‘driver’s head’ shall not exceed 275G.
Low velocity impact: Helmet impact at 6m/s. Peak deceleration shall not exceed 200G with a maximum average of 180g.
Low lateral impact: Helmet impact at 8.5m/s. Peak deceleration shall not exceed 275G.
Crush: A 10kg weight falling 5.1 meters onto helmet. Lateral and longitudinal tests. The transmitted force should not exceed 10 kN.
Shell penetration: A 4kg impactor dropped onto helmet at 7.7 m/s.Visor penetration: Air rifle fires 1.2g pellet at visor. Pellet must not penetrate the interior of the helmet.
Visor coating: Transmitter test to ensure colouration and vision is not significantly changed or distorted.
Retention system: Roll-off test and dynamic test to ensure strength of chin strap and its attachments.Chin guard linear impact: Impact test with full headform at 5.5m/s. The peak deceleration shall not exceed 275G.
Chin guard crush: Hammer hits chin guard and measures ability to keep impact away from the head.FHR mechanical strength: Test to ensure high strength of attachment points for Frontal Head Restraints.
Projection and surface friction: Test to ensure helmet surface uniformity and that friction is minimized. Shell surface also subjected to BARCOL hardness test for resistance to penetration.
Flammability: Helmet exposed to 790 Centigrade/ 1454 Fahrenheit flame; it must self-extinguish once flame is removed.
