TIRC, the kevlar stuff is usually SFI and more $$$.  General Reg 8.1, refers to classes not Speed or ET.  For ET Bracket/non Class Specific - 4.50 and slower 1/8 mile, the devices are "permitted" and not "required".  Quicker than 4.50 (Advanced ET) is required.

ET racers don't need a rule book, go to NHRARacer.com and select Rules

If you are a Class racer - have to buy the book.  If I get time and remember, I will look at my 2017 book.  Reminds me, need to call Division and re-up damn quick.
