Safety Equipment

So, I recently found myself eyeballing a fire jacket that Trmn8r was selling, I missed out on the sale, but in researching the brand/size, it would have been a poor fit for me.

So I started looking at some other brands and found the same problem. I'm 6'3" and 155lbs, so obviously skinny. So basically anything with a long enough inseam, is way too big in the waist, and anything that is long enough in the arms is way to big in the chest.

Ok, basically the story of my life, so I decide to look around for something custom.

I find Stroud Safety, and it appears that they will custom fit any of their jackets/pants/suits for an upcharge.

So I think I'll probably at least a jacket from them, and probably pants, but what SFI approval is required for NHRA drag racing at what ET/MPH?

Available options are 32a1, 32a5, 32a15, and 32a20.

Also what about the other options like cuffs, arm restraints, etc...?

Is there a ruling on full face vs open face helmets?

Is there ever a shoe or glove requirement?

Lets say I never plan on going faster than 9.50, what personal safety equipment is required for a 9.99-9.50 car?

Just wanna make sure I don't custom order something that i'm gonna need to replace in the future, thanks for reading.
