Again…… This division was created to be an affordable, entry-level way to enter stock car racing. Keeping the cars completely stock is the priority and the division will be teched to ensure that. Changes not listed in the rules are not allowed.

Tech Procedures:

  1. Three items will be teched every week without question. Tires/Wheels, Camber and Header.
  2. The inspector may opt to check any other item and will likely pick at least two items per race in addition to the three above to check.
  3. Open tech for the top 3 finishers. Any top 3 finisher can inspect the other top 3 cars with the assistance of the tech man or ask the inspector to check a specific item. One item per week may be selected by a competitor to be check on all the top three finishers cars. Item must be available for visual inspection to be selected by a competitor.
  4. The race track may inspect any part at any time during an event prior to or after the race.

Cheating/Disqualifications:

  1. First offense of cheating will result in a disqualification and loss of purse and points for the event.
  2. The second offense of cheating will result in a disqualification and loss of purse and points from the event and a subsequent suspension from the next Stock4 event.
  3. The third offense of cheating will result in a disqualification and loss of purse and points from the event as well as a 60-day ban from competing in this class.
  4. The fourth offense of cheating will result in a disqualification and loss of purse and points for the event as well as a one-year ban from competing in this class.

Cheating bans are only for the division caught cheating in. A driver may move to another division once banned from competing in one division.

Protests:
