Stilo Helmet - ST5 GT 8860 Carbon FIA-8860 / SA2015

The FIA 8860 Helmet homologation standard is meant to standardize helmet specifications for professional racing series. Most racers will not need helmets that conform to these extremely stringent regulations. Please check your rules to see if you need an 8860 helmet.

The Stilo ST5 is the new generation of full face helmet from Stilo.

The cutout for the eyeport on all ST5 helmets is taller than the previous ST4 and has a special visor to accommodate the larger opening.

Redesigned shell that optimizes shell size, airflow, visibility, and weight.
Snell SA2015 certification and FIA 8860-2010
Features a much larger visor than previous models and opens past the line of sight.
HANS ready.
Price tag includes HANS Posts.
All Stilo closed faced helmets come ready for integrated electronics, air supply, and hydration. You can use any combination of the three. The ST5 offers flexibility while maintaining a clean cabin. All options integrate seamlessly with the new ST5 from Stilo.

Features an M6 nut integrated into the shell for interfacing with Head and Neck Restraints.

What‘s Included

  • Helmet
  • Ear Cushions
  • M6 Nut pre-installed
  • 1 Clear visor
  • Optional Noise Attenuating Earmuffs

Also available with earmuffs that provide a significantly quieter environment for the driver by aurally isolating the ear. The pressure upon the head can be adjusted by replacing the special foam rubber pads placed between the earmuff and the helmet. The earmuffs unique shape ensures they stay in place and do not make the helmet difficult to put on or take off.
Visor Options - The ST5 GT 8860 comes with a 3mm clear visor for the absolute best in protection. For spares, you may choose from Clear, Yellow, Smoked and Irridium shields for driving in different lighting circumstances. All Visors mount with four specially machined aluminum fasteners and provide an air-tight seal with the rubber grommet on the helmet.

Aerodynamics - Front, rear, and IndyCar aero kits are available as add-ons

FHR Posts - M6 nut pre-installed for easy FHR Installation.

Two Shells - 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 extra small to medium, and one for large and extra large.

Stilo 8860 and Zero 8860 helmets are aimed at professional racers needing to satisfy the strict FIA 8860 regulation, or any race driver serious about helmet safety. This certification provides an unparalleled level of puncture protection as well as impact resistance. Nowhere will you find a safer helmet.


Helmet Fitment Guide


How to Measure Your Head

Measure your head as shown, around the widest part of your head. This is generally right above your eyebrows and ears. If you plan on wearing a Balaclava (we suggest it), you should measure your head with it on.

We have significantly better results with a flexible tape measure, but if one is not available you can use a string to measure your head, and then transfer that to your measuring device.


Next, reference the chart below to find which helmet size you should use. If you fall between sizes (IE if your head measures 56.5 cm) we would recommend using the smaller size.

Extra Small (54cm) 53-54 cm 21 - 211/4 65/8 - 63/4 Small Shell
Small (55cm) 55-56 cm 215/8 - 22 67/8 - 7 Small Shell
Medium (57cm) 57-58 cm 223/8 - 223/4 71/8 - 71/4 Small Shell
Large (59cm) 59-60 cm 231/4 - 235/8 71/4 - 71/2 Small Shell
Large Plus (60cm) 60-61 cm 231/4 - 235/8 71/4 - 71/2 Large Shell
Extra Large (61cm) 61-62 cm 24 - 243/8 75/8 - 73/4 Large Shell

Please Note: We have found that customers who had previously worn a 59cm (Large) ST4 helmet are most comfortable in a 60cm (Large Plus) which utilizes the larger shell size.
