*These are abstracts of the 2021 sporting regulations, and the explanatory notes and translations were made by the editorial staff of SUPERGT.net.

 

 

"Weight-handicap" is renamed to "Success-weight"

Art. 23 Success-weight System

According to each race’s result, each racing car’s performance will be adjusted (demoted accordingly) for the following race.
1. The drivers' series points accumulated by the drivers registered with the respective car (car number) until the present event will determine the quantity of loading of handicap weight.
1) Until the 6th round (time) of participation in the event in the same season:

Two kilograms (2kg) will be loaded on the car as success-weight in the GT500 Class and three Kilograms (3kg) to the GT300 Class, for every one (1) Drivers’ Series point accumulated by the driver that drove that respective car at each round until the previous round.
2) Participation in the event for the 7th round (time) in the same season:
One kilogram (1kg) will be loaded on to the car as success-weight in the GT 500 Class and 1.5 kilograms will be loaded on to the GT300 Class, for every one (1) Drivers' Series point accumulated by the drivers that drove that car at each round until the previous round.
3) Participation in the event for the 8th round (time) in the same season:
Withdrawal of success-weight. <snip>

 

*It was called "Weight handicap system" until 2020. Definition of the rule basically remains the same.

 "Weight handicap system" was adopted in 1994, the inaugurating year of the Japan GT Championship, to mandate additional weight on the car or equivalent handicap based on the race result and it has been one of the icons of the series, but the name of the rule is changed to "Success-weight system" from this season, and the handicap itself is now called "success-weight". The change is intended to emphasize more than the former name that the handicap is imposed to a team who generated a good result, and similar expression is adopted by other racing series overseas also.
 The change is only made in the name, and the format of the handicap and the weight imposed in both classes remain the same as 2020.

 

 

GTA becomes the creator of GT300 class technical regulations

Art. 25 Eligible Cars

1. Eligible car
1) GT500 Class:

(1)The GT500 Class is conforming to the 2021 SUPER GT Class 1 GT500 technical regulation (hereafter "GT500 technical regulations"). <snip>
2) GT300 Class:
(1) The GT300 Class is conforming to the 2021 GT300 technical regulations defined by GTA (hereafter "GT300 technical regulations) or GT300 mother-chassis technical regulations (hereafter "GT300 MC technical regulations). <snip>

 

*Until 2020, the eligible cars were defined as JAF-GT500, JAF-GT300, and JAF-GT300MC that conformed to respective clauses of the JAF National Technical Regulations.

 In the GT300 class race cars, the cars that were defined as JAF-GT300 and JAF-GT300MC (Mother-chassi), which conformed to respective clauses of the JAF National Technical Regulations, until last year will be built based on the GT300 technical regulations defined by GTA from this season. Therefore, the technical regulations are renamed as GT300 technical regulations and GT300MC technical regulations. For the FIA GT3 cars, the technical regulations defined by FIA will continue to be applied.

 

 

Aeros regulated for GT300 and GT300MC cars.

  

Art. 22 Vehicles and Engines

6. Application of restriction during a season to the specification of aerodynamic parts for GT300/GT300MC cars.
Changes allowed during a season to the parts mentioned below will be limited.
1) Front canard

Two types of photos and drawings must be submitted to GTA by one month before the Round 1.
Two types of replacement parts are allowed to be added during a season. Photo and drawing must be submitted and obtain approval from GTA by one month before the first event the parts will be used.
2) Rear-wing
One type of photo and drawing must be submitted to GTA by one month before the Round 1.
One type of replacement is allowed to be added during a season. <snip>

Both initial and new parts (including combination of both) are allowed to be used during the season for 1) Front canard and 2) Rear-wing.
3) Only one specification is allowed in a season for the front-diffuser and rear-diffuser of GT300 car, and photo and drawing must be submitted to GTA by one month before the Round 1.
Note: Changes are not allowed for GT300 MC since parts are clearly specified.

 

*There was no such regulations specified for JAF-GT300 and JAF-GT300MC until 2020.

 GT300 and GT300MC cars will be limited by the regulations to change the aerodynamic parts during the season from this year. Teams were allowed to change the specification of aerodynamic parts at every race until last year, and it provided them advantage over FIA GT3 cars that were prohibited to change from the initial registration of the car. This gap in rule was revisited and from this season only two types of front canard and rear-wing (combination is allowed within the two types) and only one type of front-diffuser and rear-diffuser are allowed throughout the season for the GT300 cars. GT300MC cars are not allowed to make any changes to the designated parts.

 

 

Two-group separation applied to Q1 at all races in GT300 class.

Art. 29 Practice Session (Official Qualifying Practice etc.)

2) Official Qualifying Session

The organizer will determine the entrants and the grid for the race according to the Knock-Out Official Qualifying System. In the GT300 Class, the first qualifying session (=Q1) will be divided into two groups. <snip>
5) When the official qualifying session does not take place, the starting grid may be decided based on the lap times from the official practice session, and whether to adopt such method is the discretion of the Stewards of the Meeting.

 

*Until 2020, the rule said "the first qualifying session (=Q1) may be divided into two groups" where decision could be made at each event. "When the official qualifying session does not take place" is newly added statement.

 There were two qualifying formats for the qualifying Q1 in the GT300 class until last year, single session with all cars or two sessions with cars divided into two groups, and which format to adopt was decided at each event. Single session with all cars was the standard format adopted, but grouped qualifying was adopted whenever there was a certain condition involving elements such as track, time, etc. However, the grouped qualifying was adopted at all events in 2020 after all, but from this season it is clearly defined in the regulation to adopt the format at all events.
 How to determine the starting grid when the official qualifying session could not take place was decided only by the Stewards of the Meeting, but a clear guideline to use lap times of the official practice session is specifically stated from this season.

 

 

 

 Above are the major changes in the sporting regulations for 2021, however, there are some more minor changes beside them. These changes are all for improving the safety as well as maintaining the fairness of the competition. We can be sure that all drivers and teams will take on the season opening round at Okayama with a full understanding of these revisions.
 Having these revisions in mind can help all SUPER GT fans to enjoy the sports even more as you watch the race, predict the strategy of your favorite team, or even stimulate your imagination as if you are in the driver's seat!
