Fia fire suit ratings.
Sfi ratings are determined by the results of several tests conducted on racing suits for fire retardant capabilities and thermal protective performance tpp.

That is why northstar motorsports only sells multi layer suits made from nomex and we highly recommend either a three layer suit with an fia 8856 2000 rating or a two or three layer suit with an sfi 3 2a 5 rating for all types of racing.
It is certified through sfi spec 3 3 for driver accessories and undergoes the same tpp and flammability tests as the driver suit outerwear.
