The short answer is no.
It's a question we get asked surprisingly often. Sometimes it's "Can I use my kart suit for racing cars?"
Other times it's "I've already got an FIA race suit – can I use that for karting?"
Although the two suits look very similar, they're designed for completely different jobs. They meet different FIA standards and protect against different risks.
We still occasionally see drivers turning up to track days wearing the wrong type of suit. At a race meeting, scrutineers will almost always spot it, but private testing isn't always checked as closely. Just because you've seen someone do it doesn't mean it's safe – or that it would be allowed in competition.
Why Do They Look So Similar?
From the outside, there's very little to tell them apart.
Both have full-length arms and legs, high collars, stretch panels and FIA approval labels. To most people, they look almost identical.
The important differences are in the materials they're made from and the protection they're designed to provide.
FIA Kart Suits
Modern FIA kart suits are approved to FIA 8877-2022 (older suits may carry the previous CIK-FIA approval).
They're designed to protect drivers from the things kart racers are most likely to encounter, including:
- Abrasion from sliding across tarmac
- General knocks and impacts
- Wear from constant contact with the kart
Because karts don't carry fuel systems like race cars, the fire risk is very different. As a result, kart suits aren't built to provide the same level of fire protection as a car race suit.
Instead, they're made to be tough enough to cope with the demands of karting.
FIA Race Suits
Car race suits are built for a different type of accident.
Most modern suits are certified to FIA 8856-2018 and are specifically designed to protect drivers from heat and flames.
They use fire-resistant materials such as Nomex® and multiple layers that slow the transfer of heat to the body, giving drivers valuable extra seconds to escape if a fire occurs.
That's protection a kart suit simply isn't designed to provide.
Why You Shouldn't Wear a Kart Suit in a Race Car
It's easy to think, "It looks the same, so it'll probably be fine."
Unfortunately, that's not how safety equipment works.
If you're involved in a fire after an accident, a kart suit hasn't been tested to offer the protection required for car racing. Even though it carries an FIA approval label, it's approved for karting, not circuit racing.
That's why every motorsport governing body specifies exactly which standard is required for each discipline.
What About Track Days?
This is where people often get confused.
Track days and private testing don't always have the same scrutineering process as championship race meetings, so drivers sometimes get away with wearing the wrong equipment.
That doesn't make it safe.
It also doesn't mean that same suit would pass scrutineering if you turned up to a race meeting.
When it comes to safety equipment, it's never worth relying on what everyone else is doing.
Can You Wear a Race Suit for Karting?
This is the opposite question, but the answer is just as straight forward.
A race suit provides excellent fire protection, but many karting championships specifically require competitors to wear an FIA-approved kart suit that meets the regulations for that series to protect the driver from abrasion injuries.
Race suits are designed for a different environment. They're generally lighter and less resistant to abrasion than kart suits, which is why they're not accepted for karting competition.
Always check the regulations before buying or competing.
How to Check Which Suit You Have
The easiest way is to look for the FIA homologation label inside the back of the collar.
A kart suit will display the karting approval standard FIA 8877-2022, while a car race suit will show FIA 8856-2018.
If you're buying a used suit, always ask to see a clear photo of the FIA label before handing over any money.
Buying the Right Suit
The simplest way to choose the right racewear is to ask yourself one question:
What are you driving?
If you're racing or testing a car, buy an FIA race suit.
If you're karting, buy an FIA kart suit.
Trying to buy one suit that does both jobs usually ends up costing more in the long run, whether that's because you fail scrutineering or because you're wearing equipment that wasn't designed for the risks you're facing.
Final Thoughts
Kart suits and race suits might look almost identical, but they serve very different purposes.
Choosing the correct suit isn't just about complying with the regulations—it's about making sure you have the right protection if something goes wrong.
When it comes to motorsport safety, there's no such thing as "close enough."
Buy the right suit for the discipline you're competing in, and you'll never have to worry about whether your equipment meets the regulations.
