With so many racing helmet options out there for, it can be difficult to decide which brand and model is the best for you and your team. In this racing helmet buying guide, we’ll cover the latest safety certifications, how to choose the best materials, and tips for finding the right fit so you’ll have the protection you need on the track.

Consider the Certifications

When it comes to certified racing helmets, always refer to the requirements of the circuit or venue to be sure your team is running with approved safety gear. The most common helmet ratings include:

• Snell. Snell tests its certified racing helmets for impact rating, projectile, chemical, and fire resistance. Other considerations include comfort, ease of use, and compatibility with vehicle restraints.
• FIA. Fédération Internationale de l'Automobile, or FIA, is a rating that is common in Europe and considers resistance to penetration and energy absorption in case of impact. FIA-certified helmets are designed and tested for strength.
• SFI. SFI ratings, which are similar to Snell standards, require performance minimums for retention system and shield performance, as well as impact, penetration, and fire resistance. The SFI helmet standard is accepted in a variety of USA-based motorsport circuits.
• DOT. The DOT rating is for highway use and refers to certifications on motorcycle helmets. DOT does not apply to car racing helmets.

Most circuits require Snell certification, which updates the Special Application rating every 5 years. This rating is displayed as SA, with the year the certification was last updated. For example, the rating “SA2020” was last updated in 2020 while SA2025 is the latest helmet update.

To determine if your racing helmet is Snell approved, check for the SA label on the liner or padding, or verify the certification on the Snell Foundation website.

What Is the Best Material for a Racing Helmet?

Racing helmets are built with multiple protective layers, including a lightweight outer shell (typically carbon fiber or fiberglass), an energy-absorbing inner liner (usually polystyrene or polypropylene), a polycarbonate shield, and interior padding for comfort and fit.

When choosing between carbon fiber and fiberglass, the key factors are protection and price. Carbon fiber is lighter and generally stronger, but also more expensive. Fiberglass still offers solid protection at a lower cost, making it a popular choice for budget-conscious racers.

Your best bet? Match the helmet material to your level of competition and track requirements. Whether you're looking for an entry-level option or a premium helmet with top-tier features, there's a material and build that fits your needs.

How To Choose the Right Racing Helmet Size

Finding the right helmet size starts with accurate measurements. You can get measured professionally or do it yourself to narrow down your options.

To measure at home, you’ll need a flexible tape measure and sizing charts from the brands you’re considering. Follow these steps for best results:

• If you wear a head sock or balaclava, put it on before measuring.
• Measure the circumference of your head about one inch above your eyebrows and around the widest part of the back of your head.
• Repeat the measurement three times to ensure accuracy.
• Use your largest measurement as your starting point. Try on that size first—you may need to size down, but it gives you a solid baseline.
• Test different sizes and shell shapes to find the most secure and comfortable fit.

Don’t forget to factor in helmet accessories, such as restraint systems, fresh air kits, electronics, or comms gear, and make sure the helmet you choose is compatible with your setup.

Test the Helmet for Proper Fit

A proper fit is essential for safety. A helmet should feel snug all around, with even pressure and no hot spots. When fastened, it should move with your head—not shift independently or slide when tugged.

Here’s how to check for a good fit:

• Even pressure: The helmet should hug your head without gaps or discomfort.
• Cheek pad contact: You should feel firm pressure from the cheek pads, and it should stay consistent when you press on the helmet.
• No shifting: With the chin strap secured, try gently pulling up at the base of the helmet—if it moves, it’s too loose.

Also check function and comfort: Make sure the strap fastens easily, the visor operates smoothly, and ventilation is adequate. Remember, fit varies between brands and even between models. Don’t assume one good fit means all helmets from the same brand will work. Try on multiple styles and sizes to find the right one.

How Long Do Racing Helmets Last?

Most helmets are built to last around five years, which aligns with major certification cycles like Snell, FIA, and SFI. Even if a helmet looks fine on the outside, its protective performance can decline over time due to material wear, sweat exposure, and regular use. Helmet components, like padding, chin straps, and the Energy Absorbing Material (EAM) liner, can also degrade with age, reducing effectiveness in a crash.

Plan to replace your car racing helmet at the five-year mark, or sooner if it’s been damaged in a crash or shows visible signs of wear. While five years is the general rule, most tech inspectors and tracks won’t allow helmets older than 10–15 years, or those past their certification window, regardless of condition.

How Do You Extend a Helmet’s Lifespan?

Proper helmet care and maintenance can help your helmet last longer. Start with a high-quality helmet and accessories, and inspect it carefully after every use. Always clean and fully dry the helmet, then store it in a cool, dry place away from direct sunlight or excessive heat.

Certain parts like shields, visors, and interior padding can be replaced or adjusted as needed to extend comfort and usability. However, safety should always come first: no matter how well it’s maintained, a helmet must be retired once it reaches its expiration date.

Top Auto Racing Helmet Brands

The safest racing helmets come from trusted manufacturers like Bell, Stilo, Simpson, Impact, and RaceQuip. These brands use advanced composites, such as carbon, glass, and Kevlar, to meet the most rigorous safety standards. Many models also offer modern features like integrated communication systems and cooling technology to help drivers manage heat in demanding race conditions.

While NASCAR drivers use helmets from various manufacturers, Bell and Simpson remain popular choices. Their helmets are engineered for the intensity of professional racing and built to perform under the extreme conditions of the track.

When choosing auto racing safety apparel or equipment, the helmet is an important consideration. No matter your budget, always research safety standards and track regulations to choose a well-fitted helmet that meets or exceeds the requirements.
