Stock4 Rules

This division was created to keep cars stock and create an affordable way for people to go racing from the stands to the track.

Aftermarket upper control arms and rear adjusters are allowed to achieve camber. Lower control arms must remain completely stock with no modifications.

Any Modifications done to your car previously while the camber rule was unlimited must be submitted to the tech man in writing prior to competing in your next race starting 6/3/23. Anything not submitted will be a disqualifiable infraction.

Any car that has a timecap or other weight penalties on the right side is NOT allowed to add any other weight to the car anywhere. Any infraction for added weight outside penalty weight will be punishable by disqualification for the night’s races and a 50-point penalty.

No more than 1/4″ difference from left to right on wheelbase. Zero Tolerance above 1/4″.

Safety Hubs allowed on GM cars to ensure safety.

Shock and Springs must be stock for make and model and placement. Springs can not be cut. Shocks and Springs may not be altered in any way including heating of springs or other means to collapse them.

Stock wheels only for make and model. All must be the same size and offset. An aftermarket wheel is allowed on the right front for safety but must have the exact same measurements as the other three wheels.

DOT Treadwear 400 and higher. The lowest aspect ratio of 60. Tires must be the same size on all four corners.


The body must be stock with all lights and trim and outside mirrors removed. All windows must be removed except the windshield. May use Lexan. Windshield braces are required. All interior items that are plastic and flammable must be removed. May skin doors for the roll cage.

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. 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 prior to doing it, seeking forgiveness isn’t a great plan, so plan ahead.



All cars must run lap times of 17.600 or slower to compete in this division. Any car that runs a lap time faster than 17.600 will be required to add weight as described below. Weight must be added as far to the right and centered as possible within the passenger side of the car.

Weight Penalties:
17.599-17.550 – 50 pounds added
17.549-17.500 – 75 pounds added
17.499-17.450 – 100 total pounds added
17.449-17.400 – 150 pounds added

17.399-17.350 – 200 pounds added
17.349-17.300 – 250 pounds added

17.299 and lower – DQ from race event. The car must be evaluated by the tech man to determine what can be done to allow the car to continue to compete going forward or the car will be moved to the Outlaw4 division.

– If you run a lap time faster than 17.600 in practice you simply need to add weight for the infraction. No further sanctions apply.
– If you run a lap time faster than 17.600 in qualifying (practice, group or single) you will be required to add weight for the infraction and are required to start last for the first feature.

– If you run a lap time faster than 17.600 during the first race of the night (on twin nights), you will be allowed to keep your finishing position but will have to add weight before the second race of the night.
– Timecap infractions during the race will be judged on a case-by-case basis. If you run over the limit while riding by yourself and not necessarily chasing down someone for a position, you will be required to add additional weight for the infraction. If you are deemed to be chasing down or battling for a contested position when the infraction occurs, you will likely not be penalized. These infractions will be decided on a case-by-case basis solely by the promoter.

– Sandbagging is NOT ALLOWED. There will be consequences for any driver who sandbags in an effort to steal a win.

Plan to bring weight with you if you think you’re going to be close on speed. Not having weight with you will not keep you from being penalized.

Drivers with Added Weight as of 5/30/23:
These weights have been RESET for All Offenders as Follows;
– #20 Noah Hinchee +250 pounds
– #2 Wes Givens +150 pounds
– #33G Austin Guilliams +150 pounds
– #5 Josh Brown +75 pounds

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 as well as added penalty weight will be teched weekly. Weight may be removed and weighed by tech at any time.

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.

Protest Price:

1 – Protest of the entire car is $900. $200 of the protest goes to the track, and $700 to the winner of the protest.
