ST5 FN Zero Ultra Racing Helmet (57 CM Medium) - FIA 8860-2018 SA2020

ST5 FN Zero Ultra Racing Helmet (57 CM Medium) - FIA 8860-2018 SA2020

Stilo has two separate shell sizes for this helmet. This allows us to make a better-fitting helmet that is lighter weight. Instead of filling a very large shell with lots of padding for a size small, we have one shell size for x-small to medium, and one for large and x-large.

Snell SA2015 vs 2020 …what's changed? The Snell SA2020 testing requirements have changed a small amount and have now become more in line with the FIA 8859 Helmet Standard.

Details:

Increased velocity by 5-10% for impact testing on the 2nd hit across all shell sizes.

Increased velocity from 5.7 to 6.0 m/s on the 54cm to 59cm size.

Increased peak G threshold on the 54cm to 59cm size and 60cm-64cm size.

Features:

  • Made in Italy and assembled by hand by skilled craftsmen
  • Snell SA2020 and FIA 8860-2018 certified
  • Redesigned shell that optimizes shell size, airflow, visibility, and weight
  • Eyeport on all ST5 helmets is taller than the previous ST4 and has a special visor to accommodate the larger opening
  • Much larger visor than previous models and opens past the line of sight
  • 3mm clear visor for the absolute best protection
  • Use of earbud-style earphones with an optional adapter
  • The integrated electronics jack is positioned far enough away from the HANS post anchor in order to make the use of the jack trouble-free even when the HANS is worn
  • Wiring is all positioned safely and conveniently behind the padding so as to be transparent to the user
  • Standard ear cushions
  • Earmuffs provide a significantly quieter environment for the driver by aurally isolating the ear
  • EPS cheek pads provide the best in lateral crash safety while retaining the functionality of the earmuffs to provide a comfortable aural environment for communication
  • The pressure upon the head can be adjusted by replacing the special foam rubber pads placed between the earmuff and the helmet. The earmuff's unique shape ensures they stay in place and do not make the helmet difficult to put on or take off.
  • All Stilo closed-faced helmets come ready for integrated electronics, air supply, hydration, or any combination of the three. All options integrate seamlessly with the new ST5.
  • M6 nut pre-installed for easy FHR Installation
  • Front, rear, and IndyCar aero kits are available as add-ons
