51FIFTY Jr. Late Model Series 2022
This is a nine race SERIES in 2022 and it is televised on MAVTV! "The concept for the Jr. Late Model Series is something I've thought about since 2006, as I believe a restricted late model is a great place for a youngster to hone their skills in a car they can move up with throughout their teenage years. We are proud that we have built a series where talent can shine in the Pro Late Model Series, and we have now done the same for the 10-16 year old crowd with the Jr. Late Model Series on MAVTV" Kenny Shepherd.
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.
1- Drivers must have prior racing experience and each driver must present a racing resume for approval. E-mail firstname.lastname@example.org and request a driver application

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.
