·  75 points will be awarded to all drivers that run in the "B" feature but do not qualify for "A" feature.

·  60 points will be awarded to all drivers that fail to qualify for "A" or "B".

·  Any car that takes any green flag will be paid $50.

All races will run as ASCS officials feel is to the best interest of the race program.

Provisional: Drivers in the top ten will be awarded 3 provisionals per year (excluding Knoxville Nationals and Short Track Nationals). The driver highest in points, not making the show, has first choice at a provisional and then the second and on down. No more than two provisionals will be allowed per night. Drivers using provisionals will receive the extra money only, but no additional points. Any promoter will be allowed to add any two (2) cars that they wish. Provisional rules apply to national races only.

Qualifying

1.       Qualifying heat races will be held at all events.

2.       The car count at the close of the drawing for qualifying heats will determine the number of heats to be run. As each number is drawn for a car, that number will be posted and this procedure will be repeated until a number has been drawn for each car that wishes to compete. The lowest number goes to the pole of the first heat race, the next lowest drawn number goes to the pole of the second heat, etc. Once pole position in each heat is filled, the next lowest number goes to the outside front row of the first heat, etc. If there are an uneven number of cars to equally distribute between heats, the last cars will be placed at the back of the lowest numbered heats. Any cars not represented at the drawing shall be placed at the rear of a heat race. Heat races will determine the starting position for the balance of races scheduled.

3.       The passing point system will be used to determine starting positions in feature events. The driver will receive points for passing as well as finishing position with the driver accumulating the most points from heat races starting in the pole position. Any driver failing to draw for heat races or pack racing surface (when requested) will not receive passing points, but only points accumulated through his finishing position in his heat race. In the event of a tie in passing points, the driver who first earned the points shall be aligned in front of any subsequent driver earning the same number of points. Passing points will be figured on the actual starting position on the final parade lap.

4.       Time Trials may be held at some shows, depending on car count.

5.       A car and driver qualify as a team. Each driver can qualify only one car. No driver will be permitted to change cars after taking the green flag of his qualifying heat race. An exception to this rule will be in a two day race.

6.       ASCS or their representative will advise drivers of the make-up of the number of heat races, main events, field maximum size and other pertinent information at the drivers meeting.

7.       The lineup posted on the pit bulletin board when cars enter the racing surface for any race shall be the final line-up. In the event a car drops out of the line-up for mechanical reasons, the balance of the field shall move straight forward.   The exception being if 2 cars drop out from same row, prior to green flag.

8.       The start will be official only upon the starter signaling with the green flag. In the event a pace car is used, all cars shall take their proper position behind it. In the event a pace car is not used, the pole car will set the pace which shall be consistent with track conditions and as required to keep the field in formation. ASCS shall be empowered to disqualify or penalize any driver violating this rule.

9.       A white line or Cone will be placed on the turn 4 area for all double file starts. All cars must remain in proper order until the lead car or cars reach this point. Flag man will be instructed not to throw the green flag until then. If in officials judgment the front row car or cars are out of position a yellow will be displayed, after the green and a warning given to offender. Any further violation will result in the offender being placed a row back with car behind offender being brought to front row. Any other car not in proper position in officials judgment will be penalized a minimum of 2 positions plus one position for each position gained over one. This penalty will be imposed on the next yellow or red flag. If there is no flag after penalty then it will be enforced at end of race.

10.   Any car requiring a second push on start or restart of race will be placed at rear.

11.   On all single file starts after one lap the restarts will start at a Cone to be placed on the front straight-away. The leader must start race at or near the cone and all cars must go outside of cone in the proper aligned order.   Leader must set a consistent pace.  Any car going inside of cone, hitting cone or passing a car prior to going outside of cone will cause yellow and be placed on rear. If no yellow appears you will be penalized two (2) spots for each position passed at the finish.

12.   Any car on or near the racing surface that delays the start or restart of any race shall be penalized one lap by Officials. A work area will be designated at drivers meeting.

13.   Alternates will not be taken to fill any vacancies that occur.

14.   Any car not running at a reasonable racing speed may be subject to disqualification for safety reasons.

Yellow Flag:

All cars stopping on a yellow, will be placed on the rear of Restarting line-up. An area will be designated (usually the pit area) for any work to be done during a yellow flag. Cars remaining on racing surface that are able to restart without service will be placed on the rear, in the order they were running prior to yellow flag. Any car that goes one or more laps down while in the work area or pit area will be out for that event.


Any driver who works on his car or permits any other person (other than a track official) to work on his car on the racing surface, during a yellow flag, shall be penalized one lap.

If a car needs a second push off, after any cars have started, he will start at the rear of that race.

Any car that is involved in two unassisted yellow flags will be disqualified for that event.

Red Flag:

Cars that the red flag was thrown for and any other cars that change any tire will be placed at the rear of restarting line-up. All others will get the position the were running in prior to flag, if ready to join restarting line-up when called provided they went to designated red flag work area.

It shall be the decision of the flag man and ASCS as to what cars flags were displayed for, and their decision is final.

All Restarting line-ups will be single file after one lap with any lapped cars being placed in line-up.

Note: Any car changing any tire during red flag will be placed at rear also. (Wheel spacers may be changed if monitored by track officials).

A race is not considered complete until the checkered flag appears. If a yellow or red flag must be thrown after the checkered flag appears, the race is officially over and the payoff will be done in the same manner as a yellow or red flag realignment.

Procedural: Rules shall apply to all Tour Races and other Special Races and, are strongly recommended for all weekly, sanctioned shows, and if local track rules differ they should be made known to all participants.

The belly/curl arc must span the entire length of the Center Foil and appear to be a gradual arc with the deepest point no further back than 48 inches from the leading edge. As measured on a 12-inch straight edge, the belly at 6 inches from the rear of the Foil may not be deeper than ½ inch. There is zero tolerance on this ½ inch depth. It is suggested that the wing blue print specify 15/32-inch depth, so that if any deflection or movement of the wing occurs, the depth will not exceed the ½ inch specification. (This ½ inch measurement ensures that the belly/curl arc is gradual.)

f) The belly/curl arc must start at the radius of the Center Foil’s leading edge and shall not exceed a depth of 2½ inches. Center Foil thickness cannot exceed 9 inches. Center Foil top surface from side to side must remain flat. Center Foil must be one-piece construction. No split or bi-wings will be permitted. Wings must be fabricated of metal alloys only.

i) No moving parts allowed on or in foil structure.

j) The 5” section located at the rear of the front foil must not have a bell/curl arc that is out of proportion with the rest of the front foil. As measured on a 5-inch straight edge, the belly at 2 ½ inches from the rear of the foil may not be deeper than 3/8 inch. There is zero tolerance on this 3/8-inch depth. It is suggested that the wing blue print specify 11/32-inch depth, so that if any deflection or movement of the wing occurs, the depth will not exceed the 3/8-inch specification (This 3/8 inch measurement ensures that the belly/curl arc is gradual).

k) The belly/curl arc must span the entire length of the front foil and appear to be a gradual arc with the deepest point, no further back than 12 inches from the leading edge.
