the only time you are going to see any tech differences is when the traveling show comes to your track.years ago at our little track in ark city ks.we were a nhra track but mid year the gates were locked and our money we spent to be in points to go to div finals gone.some phone calls to nhra and a sponser paid the money we were robbed of so we could go to our div finals.i guess it depends whether you want to run their finals if you become their member or not.
