Kyosho GT Masters is designed as a class for skilled drivers wishing to race at a lower performance level. Even though the motor is slower the intention is to increase competition for any given race. Therefore racers who wish to race in this class must demonstrate driving skill through qualifiers. There are 3 ways to gain entrance to this class. 

Ways to participate

1. Prequalify. Enter in Kyosho GT (Blue motor) and complete 26 laps in a qualifier or main.

2. Race. Enter Kyosho GT Masters (Green motor) prior to Jan 21 2022 and complete 26 laps in a qualifier or main.

3. Seeding race. These will take place prior to the first qualifier on a race night. You will be having a heads-up race with at least 3 cars on the track and must complete 26 laps. There will be no qualifying. There are no restrictions for a seed race, so 2 other previously qualified racers can run for the test.

Series qualifying

Instead of starting all over each race-day, results from the previous race are used to sort the qualifiers. 

• First week of competition will be random for the first qualifier with re-sorts for the remaining qualifiers and main. The final sort will determine the Mains. It will be possible to knock slower cars out of the higher main regardless of qualifying order.

• Starting with the second week and continuing, we will use previous week’s finishing order for the first heat (qualifier). Heats are in reverse order so the last place car is in the first heat with the fastest in the last heat. New racers will be put in the first heat. The remaining heats and main will be sorted based on best heat. It will be possible to knock slower cars out of the higher main regardless of heat order.
