The guys here always start with the Join the Club and get a Rule Book. Not a bad Idea but you have a credible question and shouldn't have to spend the money to join and then find out you really don't want to do this.
This is info I posted on another Forum, you have a particular Problem, right after no Convertibles.
"They do have a Street Category which is ECTA Only. and a Time Only Class for under 135 MPH, No Roll Bar, No Fire system, No Toe Strap on Accelerator, Factory Seat Belts (3 Point). No Convertibles, or Plastic Body Cars. you get a 5 MPH cushion before having to do alll the Safety Stuff."
The biggest deterrent I running into recruiting Ohio Racers to Wilmington is the Safety Tech. Almost everyone to a man (person) is "Hey I'm NHRA Legal, you guys are nuts on the inspection."
They, of course, don't understand the implications of running a mile and Safety Crew response times, and that YOU are responsible for your safety not the Fire Truck and Track personnel. This isn't the Saturday Night Drags, but there are a lot of those people here.
maybe we need a NHRA Class
