Regulation changes

Summarize
Perspective

The GTA confirmed several changes for the 2025 Super GT season.[5][6]

After a year of using the aggregate qualifying format, the qualifying system reverted to the knockout format. For GT500 qualifying, 10 cars advance to Q2 instead of 8 which previously held before. And for the GT300, 9 cars advance to Q2 from 2 groups of 14 cars. The qualifying points revert to awarding a single point for pole position in both classes.

There is also big changes in the GT300 drivers' and teams’ championship points, classified top 15 finishers able to collect points up from 10 finishers. The winner awarded 25 points while 2nd place receive 20 points. 3rd place receive 16 points, then 4th and 5th will get 13 and 11 points respectively, and from 6th to 15th, 10 points down to 1 point awarded. Also, races over 700km in length or four hours in duration no longer have a fixed points system, instead this announced by the series in advance of each round. There also the implementation of dropped scores points system in the wake of the Sepang round, in which 10 GT300 teams not able to compete in Malaysia. Only 7 of the 8 best scores count towards GT300's drivers' and team championships.[7] For the Fuji Sprint Race, the points would be handed half of the normal points.[8]

Teams are allowed to bring in 4 sets of dry and 6 sets of wet tyres for the 300km races. New: One wet tyre set must be functioning in heavy rain conditions. From Round 2 onward, GT500 tyre manufacturers who haven't won a race in 2024 may bring in one extra dry set.

During the formation lap, the distance to the car in front should be within 5 car lengths to avoid a spread out start. To avoid slow driving to save fuel when driving to the grid, a speed minimum of 80 km/h or more has to be maintained. Infractions will see a time penalty applied, along with the previous grid penalty and drive-through penalty.

To comply with a new FIA standard, carbon helmets will be mandatory from this season onward with satisfactory helmets given GTA stickers. However, there will be a grace period for drivers who can't obtain one for the opening race.

The series also announced a revision to the system of handicaps for the GT300 class, introducing the modification of refueling times as a form of success penalty. The nominal limit returns to 100 kg where previously was 80 kg, but the actual weight loaded not exceed 50 kg, and with the adjustment of refueling times added as a secondary measure to further penalize the most successful cars. This will be achieved by way of a GTA-supplied restrictor to be attached to the refueling rig, the diameter of which will be announced by bulletin prior to each race. Success ballast to continue to be accrued at the rate of 2 kg per point, with the handicap halved for the penultimate round at Autopolis and eliminated for the Motegi finale.[9]

The series also announced the second round of Fuji will be a spint format. The first race in Saturday will run 35 laps which runs like any other previous races, and two races on Sunday featuring each class respectively. For both weekend, there will be a 20-minute GT300 qualifying and a 10-minute GT500 qualifying. For the Sunday races, there will be no pit stops, and therefore no driver changes, and no success weight. Both races will be timed at 50 minutes. It is anticipated that each race will award half of the regular points compared to a standard race weekend. The Qualifying Pole Position points on Saturday by the Race 1 driver are also awarded to the Race 2 driver. In the same way, the different types of series points won by the Race 2 driver on Sunday are also awarded to the Race 1 driver.[4][10]
