Do FIA Suits Cover Events Which Require SFI Approval?
When it comes to motorsport safety gear, two acronyms often come up: FIA and SFI. These refer to different safety standards and organizations that certify racing equipment – including the all-important fire-resistant race suits. If you’re a UK driver wondering whether your FIA-approved suit will be accepted at events that call for SFI approval, this post is for you. We’ll break down what FIA and SFI certifications mean, which types of events in the UK require which standard, and whether an FIA suit can be used when SFI is asked for. We’ll also give some gear recommendations from our GSM Performance range to keep you safe (and legal) at the track.
FIA vs SFI – What’s the Difference?
FIA Standards
FIA stands for the Fédération Internationale de l’Automobile, which sets global safety rules for motorsport. FIA-approved race suits are tested to high standards and must meet regulations like FIA 8856-2000 or the newer FIA 8856-2018. These suits are fire-resistant and designed to protect you from heat and flames for up to 15–18 seconds. You’ll find an FIA label and expiry date sewn into the suit, and full FIA gear usually includes fireproof gloves, boots, and underwear too.
SFI Standards
SFI is short for the SFI Foundation, Inc., an American group that certifies race gear, especially in drag racing. SFI suits use a rating system like SFI 3.2A/5, where the number indicates the level of fire protection. For example, a 3.2A/5 suit gives about 10 seconds of protection. Higher ratings like 3.2A/15 or 3.2A/20 are for faster or more dangerous drag racing classes. SFI suits have a tag with the rating, but don’t usually have an expiry date like FIA suits.
Key Differences
The main difference is that FIA suits are required for most UK and international events, while SFI suits are more common in American racing and UK drag racing. FIA suits are approved as a complete package and have a clear expiry date. SFI suits are rated by performance and don’t expire in the same way. Both types are fireproof, but you’ll need to match your suit to the type of event you’re entering.
The bottom line: Both FIA and SFI-rated suits are fire-resistant and built to protect you in a racing fire. However, they are overseen by different organizations and are labeled differently. Whether an event will accept one or the other depends on that event’s rules, which we’ll explore next.
UK Event Types and What They Require
Circuit Racing
For circuit racing in the UK – including everything from club-level track days to professional series – Motorsport UK requires FIA-approved race suits. These suits must meet at least the FIA 8856-2000 standard, though many events now prefer the newer 8856-2018. SFI-only suits won’t be accepted, even if they’re rated to the same fire protection level.
Rallying and Stage Events
Rallying is also governed by Motorsport UK, and the rules are very similar to circuit racing. That means you’ll need an FIA-homologated suit for stage rallies, road rallies, and hill rallies. Some national rally events may still allow suits made to the older FIA 1986 standard, but most drivers opt for modern FIA 8856-approved gear to cover all bases. You’ll also typically need FIA-approved fireproof underwear, gloves, and boots – so it’s worth investing in a full FIA kit.
Drag Racing
In the drag racing scene – especially at places like Santa Pod Raceway – SFI standards are common, with SFI 3.2A/5 being the typical requirement. However, FIA 8856-rated suits are also explicitly accepted in many UK drag events as an equivalent. Just make sure your suit is in good condition and within 10 years of its manufacture date.
Higher-powered drag cars may require SFI 3.2A/15 or /20 suits, especially when running on methanol or nitro. In those cases, an FIA suit might still be allowed if you wear fireproof underwear underneath – but check the event rules to be sure.
Drifting
Drifting events can vary in what they require. Some follow Motorsport UK rules and require FIA suits, while others (like independent drift leagues) allow a wider range of fireproof suits, including older FIA standards and Proban suits. While SFI suits may be permitted in grassroots events, an FIA-rated suit is usually the safest choice for broad event access and scrutineering approval.
Can You Use an FIA Suit in an SFI-Required Event?
In most UK events that mention SFI suit requirements – especially in drag racing – an FIA-approved race suit will be accepted as equivalent. For example, Santa Pod’s rulebook clearly states that FIA 8856-2000 or 8856-2018 suits are allowed instead of SFI 3.2A/5. So if you’ve got an FIA suit, you’re usually good to go for drag racing and similar events.
That said, it’s always smart to double-check the event rules. Some organizers might strictly ask for an SFI label, especially if they follow American rulebooks to the letter. If FIA isn’t mentioned, contact the organizer before the event to confirm.
Keep in mind that FIA suits are generally equal to SFI-5, which covers most amateur racing. If the event requires a lower rating like SFI-1, your FIA suit still works. But if it calls for SFI-15 or SFI-20, like in top-level drag racing, you’ll likely need to upgrade your gear or add FIA-approved fireproof underwear.
Also, remember that FIA suits expire (usually after 10 years), while SFI suits don’t technically expire but still need to be in good condition. Worn or damaged suits can be rejected at scrutineering, regardless of certification.
Lastly, the reverse isn’t true – SFI-only suits aren’t accepted in FIA-regulated events like circuit racing or rallying in the UK. So, if you race across different disciplines, the safest option is a dual-certified suit that meets both FIA and SFI standards.
Choosing the Right Gear – GSM Performance Recommendations
Best of Both Worlds
If you take part in a mix of events – like circuit racing and the occasional drag meet – we recommend a dual-certified suit. The OMP First-S is both FIA 8856-2018 and SFI 3.2A/5 approved, so it’ll pass scrutineering at almost any UK event. It’s affordable, comfortable, and ready for anything from track days to rally stages and drag strips.
Drag Racing Focus
For drag-only drivers, we stock SFI-rated suits like the OMP OS10, ideal for RWYB days and grassroots drifting. Just keep in mind that SFI 3.2A/1 suits are single-layer, so we suggest pairing them with fireproof underwear for extra protection. If you’re running faster cars or stepping into competition classes, go for a multi-layer SFI 3.2A/5 suit or a high-spec FIA one. Need an SFI 15 or 20 suit? Get in touch – we’ll point you in the right direction.
Gloves, Boots, and Safety Accessories
We carry both FIA and SFI-certified gloves, boots, and accessories. FIA-rated gear is accepted at most UK events, and works for drag racing too. For those needing SFI labels specifically – like for U.S. rulebooks – we offer gloves and shoes from brands like RJS and RaceQuip.

Drag Essentials
If you’re building a drag car, don’t forget extras like arm restraints, neck braces, and fire suppression systems – all of which may need to meet SFI specs. We’ve got SFI-approved options, including the popular Lifeline Zero 360 system.
Helmets and FHR
Helmets need to meet current FIA or Snell standards. We stock models that are accepted at UK circuits and drag strips. If you’re going really quick, a Frontal Head Restraint (FHR) may also be required – our FIA-approved options are ready for both track and strip use.
FIA or SFI? Here’s the Bottom Line
In UK motorsport, FIA and SFI are two different safety standards, but they often cover similar ground. If an event in the UK asks for SFI-approved gear, an FIA 8856-rated suit will usually be accepted, especially at places like Santa Pod where both standards are listed in the rules. FIA suits offer excellent fire protection and are widely trusted across racing disciplines.
That said, always check the specific event requirements. If you compete in different types of events, it’s worth choosing a suit that meets both standards. At GSM Performance, we’re here to help you find the right racewear – whether you need FIA, SFI, or both. Our team can guide you through what’s required and recommend gear that keeps you safe, legal, and ready to race.
