All Body Parts Must Be on the car at all times. Any body part not on your car, you will need to add 50 pounds of lead weight in its place. Mounted on the far right side of the car, as close to the door as possible. This includes the trunk or hatch of your car. The part must be attached in its original shape and size or as close to it as possible with damage. (The only exclusions to this rule, will be parts unattachable after a wreck during a race night.)

The car must be in presentable condition at all times. We ask that you take pride in the cars that you are racing. Cover the headlight openings and other holes left by car preparation. Paint the car nicely and come up with a unique look for your car and keep it in as good of condition throughout the season as you can.


Roll cage – Minimum 4-point cage required with three door bars on the driver’s side and 2 on the right side. See roll cage components website for circle track start kit for the style of cage required. Roll cage must be welded in the car not bolted. If you need help with getting a cage installed call Langley Austin at 276.613.4208 and he will point you to someone who can help.

Safety – Aluminum Race seat and Five-point harness required. Window net must be mounted solid on bottom and latch release on top. Fire extinguisher with metal mounting bracket a must. Helmet, driving suit and gloves are Mandatory.

Anything related to safety is likely allowed within reason, but you must ask before doing it. Forgiveness is harder to come by than permission. Anything not discussed in these rules should be addressed with the tech man before doing it, seeking forgiveness isn’t a great plan, so plan.


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 – Tires and Wheels will be teched weekly.

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 finishers 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 checked 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.


1 – The 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.


1 – A protest must be submitted in writing, specifically outlining what parts are being protested and must be accompanied by cash for the protest amount. This must be done within 10 minutes of the checkered flag.

2 – Protest must be submitted to the lead technical inspector for the night for your division.

3 – Car being protested will be asked to accept or deny the protest at the time in which the inspector accepts the protest.

4 – If the car being protested has been penalized for the part in question already during pre-race inspection, the protest will be disregarded. That penalty must be written and taped to the car before the race by the tech man on the right of the windshield.

5 – Protests will not be accepted on championship night so as not to allow a competitor the chance to alter the outcome of a championship on the final night of points racing.
