❓ Frequently Asked Questions

Q: Can I use an FIA suit in an SFI league?
A: Yes, in most U.S. leagues. But the reverse is not always true — SFI suits are usually not accepted in FIA-level karting or F4.

Q: What does SFI 3.2A/5 actually mean?
A: It’s a safety level where the suit must resist 10 seconds of direct flame and provide a Thermal Protection Performance (TPP) of 19+.

Q: What’s the cost difference?
A: FIA certification can add $40–$100/unit in cost due to materials and homologation. SFI suits are more budget-friendly.
