Pro Late Models

Pro Late Model Series 2022

All nine races of the Series will be televised on MAVTV!

For 2022 this is a nine race championship series and all nine races of the Series will be broadcast nationwide on MAVTV. This is a TELEVISED SERIES in 2022, the dates for the 2022 season are March 5th, April 2nd, April 23rd, May 21st, June 25th, July 30th, August 27th, September 17th, and the Big Short Track Shootout show on October 15th.

"The concept for the Nut Up Pro Late Model series grew from a series of Open Shows I promoted beginning back in 2006 with the last one being in 2011, and the rules evolved from those races. I learned we could have a very competitive series that is enjoyable for our drivers to compete in, while at the same time only having roughly a dozen rules that are easy to understand and follow. The key is to insure it is a driver's class, and not a horsepower class. With that said, for 2022 we have a format with minimum rules and maximum competition. Again, the intention of this class is to provide good competition with a variety of race cars, and the tire not being able to get all the power to the ground is a key component to the long term success of this class that has influenced adjustments in the rules. We are proud that we have built a series where talent can shine, and now that talent shines on nationwide on MAVTV for the 8th consecutive season" Kenny Shepherd.

Madera Speedway Race Procedures

Starts and Restarts – 2022 Procedures;

When the leaders hit the one to go at the flag stand the yellow track lights will go out and the front row will maintain pace car speed with no tire scrubbing past the flag stand. When the pace car pulls off the track the front row will maintain pace car speed until they get to within a car length of the acceleration cone/line in the middle of turn three and four. When the front row gets to the accelerate cone/line they are to gradually build speed starting at or about a car length prior to the cone/line. The race leader will be the first car to cross the starting line and will be guaranteed to lead at the starting line as long as they began to gradually accelerate at or slightly before the start cone/line and the leader does not spin the tires or decelerate in anyway after they passed the “acceleration” cone/line. If the leader does not gradually accelerate at the acceleration area, or accelerates late or abruptly, or pinches the second-place car up or down, or spins the tires, or decelerates at any time after the acceleration cone/line they will forfeit their right to lead at the starting line.

If the leader has provided a good start and the second-place car beats the leader to the starting line on the start, or a restart the green flag will remain out and the second-place car will be black flagged and will have three laps to drop back to the last place position on the race track under green. If a caution comes out prior to the second-place car dropping back to the last position they will restart at the rear of the field. If there is a restart with five laps or less remaining in the race and the second-place car beats the leader to the starting line after the leader has provided a good start the caution flag will come out when the cars are on the back stretch and the second place will be moved to the last position for the next restart. Note, If the leader does not provide a good start and the second-place car beats the leader to the starting line the green flag will remain out and there will be no penalty issued to the second-place driver. The leader will have their choice of high or low for all restarts.

Starts and Restarts – 2022 Coming Update;

The procedure with remain the same for 2022 with the only exception being the second-place car will drop to the third position on the track if they beat the leader to the starting line and receive a black flag after the leader has provided a good start.

• Caution Flag Procedures: When the Caution Flag is displayed, you are to slow down in a safe manner and proceed with caution back to the start /finish line single file. No Racing or Passing. Stay in Line. Violators are subject to penalty. Your restart position will be the position you were in the previous completed lap unless you are deemed to be involved in the incident that brought out or led to the yellow flag being displayed. If you are directed by Race Control to correct your on-track position, you must do so within 2 laps or you will be penalized 1 lap and will no longer be eligible for a Lucky Dog. If you are involved in an incident causing a caution flag you will be sent to the rear of the field. Caution Flag laps may be counted if we deem necessary.

• Involvement: If you are deemed to be the cause of an incident or involved with it, you will be placed to the very rear of the Field. Cars may be parked if charged with causing 3 on track incidents. Rough driving will not be tolerated as well as any retaliation. Depending on the incident, you may be parked, issued a fine, and penalized.

• Lap Down Cars: All lap down cars will be moved to the rear on all restarts. There will be a Lucky Dog on every yellow flag giving one driver the least amount of laps down, one lap back and putting them to the very rear of the field unless the eligible car was involved in the yellow flag incident. ALL LAP DOWN CARS MUST STAY ON THE BOTTOM OF THE TRACK when being passed by the leaders of the race.

• Blue Flag; Blue flag means move over, the leaders are coming. Follow the Flagman’s direction and move to the bottom of the Race Track. Make sure you hold your line. Use hand signals to notify Drivers of your intentions

• Black Flag: Black flag pointed at you is a warning in regards to your actions on the track. If it is displayed, you must go to the pits within 3 laps

• Red Flag: Red flag means stop in a safe manner and follow Track Officials directions. Only Cars in the Hot Pits may be worked on.

• Hot Pits: If you enter the Pits for any reason you will restart at the rear of the Field.

• Tires: Cars must start and finish the Main Event with the same tires they qualified with. Any tire changes after Qualifying must be approved. Driver will start at the rear field and tires will be subject to impound by Race Control

1. The main event line-up will be set by a card draw; all in the top ten will draw for their starting spot unless the race director feels the need for a straight up start due to the amount of caution flags in a previous race.

2. Teams can work on their race cars all the way up until the green flag of the first 50 lap segment without penalty, or position loss.

3. Teams can work on their cars at the halfway break, they may change anything they want except tires (the four marked tires can change locations on the car at the half time break, example, the right front and right rear may be exchanged), and each car must remain on the tires the car qualified on. A team may work on the car before the green flag of the second segment without penalty, or loss of position.

4. If a car is worked on after the green flag has been thrown for either the first 50, or second segment, then the car must re-enter the race at the rear of the field.

5. Championship points are awarded for the main event with 50 points going to the race winner, 48 for second, 46 for third and so on... There are bonus points for the segment leaders in each race, 1st-5 bonus points, 2nd-4 points, 3rd-3 points, 4th-2 points, and 5th - 1 point.
