Stilo ST5 GT Zero 8860-2018 Carbon Helmet

CMS Stilo Helmet Owner's Kit

The Stilo Helmets ST5 GT Zero 8860-2018 carbon helmet was designed for professional racers needing to satisfy the strict FIA 8860-2018 regulation. It’s also the helmet of choice for drivers who won’t compromise their safety, no matter where they’re racing. This certification provides an unparalleled level of puncture protection as well as impact resistance. Try as you may, you won’t find a safer, lighter-weight helmet anywhere.

The Stilo Helmets ST5 GT Zero 8860-2018 carbon helmet is the lightest-weight carbon fiber racing helmet on the market (weights listed below). It can be outfitted with integrated electronics, forced air, helmet eject system, and a hydration system for those racers who like to stay hydrated on the track (particularly useful for endurance racing). Thanks to an innovative design which incorporates mounting and routing for these options at the time of manufacture, integration is sleek and seamless with nothing protruding from the helmet, hanging down or otherwise getting in the way. When not in use, you don't even know these features are there.

Looking for increased visibility? The Stilo Helmets ST5 GT Zero 8860-2018 carbon helmet has a taller and lower eyeport, giving you better visibility without compromising your safety. Each visor has a center pinch-clip to make opening and closing easy even while wearing nomex racing gloves.

For the "Naked" version of this helmet (without side ports), please see the Stilo Helmets ST5 N Zero 8860-2018 Carbon Helmet.

This helmet will ship to you with signature required for delivery.

How to Measure Your Head for a Helmet

Sizing note: We have found that customers who typically wear a size 59 helmet are more comfortable in size 60, which uses the large shell. Please order accordingly.

FEATURES

  • FIA 8860-2018 Certified
  • Significantly lighter than the previous ST4 helmets
  • All ST5 shields are now interchangeable across all ST5 helmets
  • Includes standard HANS post anchors
  • Includes Stilo bag for your helmet and HNR
  • Eight ventilation holes for use with Stilo Helmets Top Air systems
  • Re-designed cheek pads are more contoured and comfortable than previous ST4 helmets
  • Stilo ZERO shells are the lightest FIA 8860-2018 helmets available

WEIGHT (including intercom)

  • Small Shell: 1130 Grams / 2.49 lbs up to size L (59)
  • Large Shell: 1230 Grams / 2.71 lbs up to size 3XL (64)

An effective helmet is one that fits properly. Have an assistant use a measuring tape, or a piece of string to measure the circumference of your head starting at a point approximately one inch above the eyebrows in front, around a point in the back of the head that results in the largest possible measurement, and finally wrapping back to the front. It's a good idea to take several measurements to make sure you have the largest one.

FIA 8860-2018 TESTING

Here are some of the standards an 8860-2018 helmet has to meet:

  • Standard impact: helmet impact at 9.5 m/s, peak deceleration on driver’s head < 275 G
  • Low velocity impact: helmet impact at 6.0 m/s, peak deceleration < 200 G
  • Low lateral impact: helmet impact at 8.5 m/s, peak deceleration < 275 G
  • Advanced Ballistic Protection(ABP): a 225 g metal projectile fired at 250 km/h, peak deceleration < 275 G
  • Crush: a 10 kg weight falling 5.1 meters onto helmet, lateral and longitudinal tests, transmitted force < 10 kN
  • Shell penetration: a 4 kg impactor dropped onto helmet at 7.7 m/s
  • Visor penetration: air rifle fires 1.2 g pellet at visor, pellet must not penetrate the interior of the helmet
  • Visor coating: transmitter test to ensure coloration 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 5.5 m/s, peak deceleration < 275 G
  • 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 790o C/ 1454o F flame, must self-extinguish once flame is removed.
