I noticed some suits are rated sfi-5 some are rated sfi-1 is one best or is 5 I'm guessing 5 because the suit are almost always more expensive, do the numbers stand for how good they are at protecting you from a fire?

Keep in mind, that's for a single layer of fabric.

Buy as much suit as you can afford. I wouldn't want anything less than 2-layer coveralls plus the the Nomex underwear. I plan on picking up a 3-layer suit and the underwear for a total of 4 layers. The more burn time you can get, the better. The moment you're having trouble getting out of a burning wreck, you'll be wishing you paid for the extra burn time regardless of what it cost.

From the SFI page: The TPP test can be used to evaluate multiple-layer configurations as well as single-layer fabrics. The samples used in testing are assembled with the identical fabrics and layer order as an actual driver suit.

So the rating is for the suit as constructed. The number of layers does not necessarily affect the rating. As an example, I have a Bonneville/top fuel suit that is only three layers, but it is rated at SFI 3.2A/20 and is the highest rated suit Diest sells.

I would rather have a GOOD two layer suit than a cheap three layer if I knew the two layers were made from newer, better performing material.

Thawley where can I get this suit your talking about the best I have been able to find online is a 3.2A/5 suit I am a safety nut and want the best I can get.

 

Dood, you do NOT want a /20 suit for road racing and track events. I call it my "oven mitt". I only use it for Bonneville and only at the last minute. It is the hottest, thickest, most miserable thing I have ever worn in my life. I only posted to point out that "what's it's rating" is more important than asking "how many layers". The rating on the suit is what matters.

Just get a good /5 (like Simpson, Sparco, Alpine Star, etc.) and some Nomex undies. Fire doesn't care whether its a $300 /5 or a $1000 /5. The differences in price usually reflect differences in quality, breath-ability, durability and style. Buy it loose, rather than tight.

PS: To answer your question, Simpson & Diest both sell top fuel /20 stuff. But you really don't want it unless you need it (drag racing, Bonneville or Burning-man movie stunts...)

 

HAHAHAH ok misunderstood ya I heard they were way to thick but thought you were using it so i was gonna see what you thought about it.

ok sfi-5 it is.

 

I really enjoy my alpinestars suit which is an SFI 3.5 or something like that it has the highest rating without being an oven mit. It's nice and breathable and fits well. However i haven't actually raced with it yet but the quality is superb

 

Thanks all have to look into them.
