Stilo's ST5 GT line of racing helmets are engineered for maximum flexibility to integrate into any racing environment. The Stilo ST5 GT Carbon features a lightweight carbon shell with a taller eyeport to allow 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. Side-mounted ports allow for the easy integration of intercoms, hydration systems, forced-air, or all 3! 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.
