Looking for a Kevlar/Carbon Fiber Composite helmet with great visibility and endless customization options? The ST5 GT is Stilo's latest and greatest Kevlar/Carbon Fiber Composite helmet. They've updated the design of the ST4W GT that was so popular to include a taller and lower eyeport, giving you better visibility without compromising safety.

That's not all they've accomplished for the new model, however. Here's a list of upgrades and features on this helmet:

  • Lighter weight compared to ST4 models – up to size 59 in the small shell!
  • Now available in 3XL (64) in addition to 2XL sizing (composite versions as well as carbon)
  • All ST5 models share the same eyeport, so shields are now interchangeable across all ST5 helmets.
  • Greatly improved ventilation: Now with 8 ventilation holes for improved cooling with Top Air systems - 6 in and 2 out
  • Narrower by almost ½” and even lower profile than the ST4
  • New & improved visor: only two screws and a center “squeeze to unlock" latch system
  • Newly designed cheek pads are more contoured and comfortable than any previous Stilo helmet

The modular design of the ST5 GT means that it can be outfitted with electronics, air supply or hydration systems (as well as any combination of the three), with no wires or hoses hanging from the helmet as it all integrates within the helmet shell.

Lightweight and strong, with the flexibility to work seamlessly with your onboard systems – the Stilo ST5 GT is a great choice for any racer who yearns for enhanced visibility without compromises. Check out the additional features of ST5 GT below:

  • FIA 8858-2010 and Snell 2015 Certified
  • Lightweight - size Large weighs a mere 3.6 lbs!
  • Kevlar/Carbon Fiber composite construction
  • Comes with noise attenuating earmuffs as standard
  • Includes an M6 nut integrated into helmet shell for use with head and neck restraints.
  • Three different shell sizes to choose from, providing you with a better fit and a lighter helmet. Rather than filling a large shell with lots of padding to accommodate those who require a small size, Stilo offers 3 shell sizes; one for extra small to medium, one for large and extra large, and one for 2X and 3X large sizes.
  • Electronics Systems Features:
    • An integrated electronics jack that is positioned far enough away from the HANS post anchor so that use is trouble-free even while wearing a head and neck restraint.
    • Wiring that’s integrated behind the padding for minimal hassle. With no hanging wires in the helmet, everything stays put where it is supposed to be.
  • Ventilation System Features:
    • Available with an air supply system that pumps in a steady supply of fresh air to drivers of closed cockpit cars. Many different attachments are available, all of which integrate into the helmet shell seamlessly, and can be used in conjunction with a communication system as well as a hydration system.

Great Experience !

Visited the SoCal location to shop for a Bell Helmet during my vacation but after talking to Peter the Retail Manager I ended up buying a Stilo ST5 & I couldn't be happier as it fits like a glove. Peter was friendly, helpful & patient with advice for my many questions & I ended up purchasing a Stilo Replacement Shield & a pair of Alpinestars GP Racing shoes too. My e-mails have been answered promptly & the delivery time of items for self collection as promised. All in all I had a great experience dealing with Winding Road Racing thank you !

very comfortable, high quality

Excellent helmet and a great value for the money - I actually upgraded to this helmet (with built in comms) after suffering thru a hot weekend in a lesser priced variety. One of my better decisions lately!. The comfort gain is truly significant.
This helmet is light, offers great visibility, built in comms are of excellent quality, the helmet remained cool in the florida summer heat and fit perfect right out of the box. Highly recommend , Stilo is deserving of their good reputation.

New Helmet and accessories

Ordered over phone which was helpful for me to get advice from the experienced person who took my call. I added hydration and electronics which can be done in numerous configurations. Just used the setup at COTA this past weekend and was very pleased with the fit and quality. WR was also at the track and was able to get further advice from them on cleaning the visor which was critical, otherwise I likely would have messed up the anti-fog coating on the inside. That's to the WR guys for all their quality support!!

Stilo Helmet ST5

Nice helmet! Air and Comm included is very well done. Ensure to try on if possible. Large helmet size is tight on face. Nice selection of replacement cheek pads available.

Make sure to get 1 size larger.

As a driver and an instructor I needed a lighter helmet and a way to use my radio to speak to my students without the wires being in the way. This helmet is amazing! If you go by the helmet sizing chart remember that this is the old chart and the new helmets run smaller. I measured at 57cm medium but decided to get the 59cm large helmet. Glad I did. Large fits perfect. Medium was the size of my last helmet and noway would a Stilo medium (57) fit me. Helmet is lightweight and well designed. You will not be disappointed. Will be using it for the first time in 2 weeks at RA as an instructor. Winding Road has a great reputation and cost was comparable to others.

Worth the investment

As an Instructor for Porsche Club, BMW Club and Fast Toys Club I ride with a variety of Students with dramatically different skill sets. I made the decision to spend more on a lighter helmet because I jump in and out of so many cars. Since last November I have been struggling with nausea and I was surprised that a lighter helmet would completely eliminate that issue. One of the very impressive options on the helmet is that it comes with a variety of different padding options. When I auto cross a comset is not usually practical so I can remove the ear pieces but on the track the ear pieces make it easier to hear my students than if we were in a quiet room. I have become a Stilo fan!
