The NASA Club Codes and Regulations require the use of a racing seat in racecars. It’s also a good idea to have one in dedicated Time Trial cars. For street cars, that’s a tough call to make, although it’s happened more than once that when an owner installs a racing seat, the car gets used less often on the street. It’s a slippery slope.
Of course, buying a seat for your racecar involves several choices beforehand. For example, any seat that is not homologated by the FIA is required to have a back brace. Those are for the most part aluminum seats, which are not included in this roundup. FIA-homologated seats for closed-cockpit cars are in all cases made from composite materials such as fiberglass-reinforced plastic or the more lightweight carbon fiber. FIA homologation comes with the added benefit that the seats don’t need a back brace before their expiration date, but would be required to have one after the seat has “expired.”
Here’s how the NASA CCR spells out the need for back braces in section 15.6.21:
“An exception may be made for those seats homologated to, and mounted in accordance with, FIA 8855-1999 or 8862-2009 standards. Those seats that qualify for the aforementioned exception must conform to the entire FIA 8855-1999 or 8862-2009 set of regulations, as applicable. This includes a mandatory seat replacement, or use of a seat back brace, for any seat more than five (5) years old (8855-1999) or more than ten (10) years old (8862-2009).”
Racetech offers composite FIA seats with accommodations for seat brace built right into the back, but that’s a rarity. Most FIA seats don’t have back-brace brackets or bolt holes, but they’re also not necessary if you want to brace them according to 15.6.21, which says a back brace “need not be attached to the seat itself.”
Another NASA rule in section 15.17.9 states that, “All vehicles, except formula cars, must be outfitted with a right-side impact head restraint system. A seat with a “bolster” to keep the head from moving to the right side in an impact is acceptable. A side-impact head-net restraint system, such as shown in picture 15.17.9-2 below, is also acceptable.”
However, it’s become common knowledge that a right-side net isn’t as good as a full containment seat, with the full “halo” to surround the back and sides of the driver’s helmet, and that a full containment seat is well complimented by a right-side net.
When shopping for an FIA-homologated seat, there are at least a few things to consider. One is the FIA ratings themselves, which can be a bit obscure. FIA 8855-2021 is the newest standard. The 8855-1999 seat standard has not been nullified by 8855-2021 and possibly will not be due to the effect the standard has on pricing. Seats with the 8855-1999 ratings are going to be more affordable than the top-tier 8862-2009 standard and the new 8855-2021. The good news is that the new 8855-2021 seats have a 10-year lifespan compared with five years on the 8855-1999 seats. That’s great news.
Those standards tend to affect price most, but other considerations when choosing an FIA seat are the size of the driver and the size of the cockpit in which it’s being installed. Of course, weight is always a concern for racing cars, so where carbon-fiber options are available, they typically cost more than fiberglass seats.
We worked with NASA’s official equipment supplier Competition Motorsport and some other manufacturers to put together a roundup of some of the FIA-homologated seats on the market. CMS has a good YouTube video on how to fit yourself for a racing seat. Most of them are of the containment variety, but some are non-halo models in here with the 8855-1999 rating.
This is not a complete selection of everything on the market, but a good cross section of some of the most popular FIA-rated seats available currently.

Shape shape shape! All of these features are meaningless if you’re swimming in a seat, sink too deep, or can’t fit your derrière into a narrow opening. Just like helmets, every manufacturer is significantly different in their shape designs.
Very surprised to not see the Momo Lesmo One seat. It’s what I’m running and I absolutely love it.
