Here is another one Racers

Seems every track you go to has different "Language" for differant classes of drag's--So when building a car do you strictly go by NHRA rule book when building a car from scratch???? We are going to RSD on Friday night at a local track and are going to pick up a rule book and also take the Duster (street) down the track a few times.Also does the rule book spell out exactly what each class needs????? example if we run sportsman do we need a full interior in the car????? if we run pro do we need a 8 point cage or a 6 point cage--Does it spell this all out??? THanks Steve
