Title: Under 175mph Suit clarification
Post by: TCWorley on July 14, 2017, 11:16:50 AM: Hey guys,

Rookie driver here hoping to clarify the rulebook notes on necessary suit ratings. The rulebook says the following: "SFI 3.2A/10 or /5 with full Nomex underwear"

So, I'm trying to decipher if 3.2A/10 is goo w/o underwear and I only need it with /5 or if they BOTH require Nomex Underwear? Anyone able to clarify this for me?

Many thanks in advance!

-T.C.

:cheers:

If you're on fire, you want everything you have.... they listed the minimum... max is a 20 with underwear....

You are best to find a 15 or it your planning on staying around look for a 20. We have both bought new but already made but would fit. We have a 5 for our 1/2 mile dirt car but only need a 1...I guess we are firesuit poor.

1> [SFI 3.2A/10 or /5] with full Nomex underwear

or

2> SFI 3.2A/10 or [/5 with full Nomex underwear]

However, the phrase is defining a minimum requirement, so it's not likely that 1> was meant (more than one minimum).

I have some buddies that race and own suits they'd loan me, but they are not labeled as SFI certified. Guessing the FIA certifications aren't accepted? Anyone know?

1)SFI 3.2A/10 a suit by itself that is rated 10.
2)"or /5 with full Nomex underwear"
a suit that is rated for 5, + set of underwear Nomex /Kevlar adds 5 for a total of 10.
