More than likely, you can do as you say and have no trouble from the Tech Inspectors, as long as you aren't making the 10.99 or 140 mph marks. Soon as you get fast enough, safety will be Top Priority, whether YOU think it is, or not. Insurance companies are putting pressure on the track owners, to keep it safe as possible and save them money. Most of the racetracks around here have gone to 1/8 mile racing, in the last few years, because of it.
