The “Super Taikyu” Philosophy

Super Taikyu 2020 Sporting Regulatiolationn & Technical Regulation

In 1991, the Super Taikyu Race (“S-Tai”) began as a participant-focussed competition for mass-produced cars. It is the biggest race of its kind in Japan. This is a team sport in which both professional drivers and amateurs (for whom racing is an essential part of their lives) work together to nurture and develop both themselves and their sport. The atmosphere at Super Taikyu is like a gathering of car-mad, motorsport- loving friends. Through these meetings we hope personal bonds will be deepened, that participants will encourage each other while competing fairly in a demonstration of good sportsmanship. In other words, Play Fair and Compete Hard! We also strive to develop the sport of racing itself through the improvement of technologies in an environmentally-conscious way. Fair competition with safety as a priority is paramount, but it should not all be about the struggle for rank. We want to create an enriching experience for all who take part. Nothing puts your mettle to the test like continuous, personal challenge. We also aim to contribute to the advancement of Japan’s automobile industry and motorsports market through the development and sales of auto equipment and parts developed with Super Taikyu participants’ know-how and experience.

It is our hope that everyone associated with Super Taikyu share and appreciate this philosophy. Let us put our stamp on motorsports and join hands in passing along to the next generation an even richer racing tradition.Super Taikyu 2020 Sporting Regulation

Group 2: ST-4 and ST-5 Allocation of starting grids when in a two race event – Classification can be found in the Supplementary Regulations in each round and the starting grids will be allocated for each race. Pole position on the grid is always inner side toward 1st corner throughout all the circuits.

When there is a two-race event based on the qualifying order – if the number of cars in the class are less than 10, classification according to the qualifying order will not be established and instead, the cars of the class concerned will be allocated in other class races. Provided the previous clause (4) is fulfilled, starting grid in each group will be established based on the combined fastest lap time of the qualifying lap time set by Driver A and Driver B. In the event of a tie, combined second best times of Driver A and Driver B will be taken into account. Ordering priority giving to the teams to set the grids of the Race is as follows: 1: Both Driver A & B cleared the standard lap time for qualifying 2: Either Driver A or B cleared the standard lap time for qualifying 3: Neither Driver A nor B cleared the standard lap time for qualifying (7) If Driver C and D are registered in the race, these drivers must be timed in the respective qualifying practice as set in the time schedule. (8) In order to be qualified for Driver C and Driver D, the standard lap time must be at least 110% of the average time of top three drivers in the qualifying session in the respective class. The qualifying results of Driver C and D do not affect on establishing grids. If the number of cars that passed the scrutineering exceeds the number of grids, the following rules will apply to determine the number of cars admit for the Race. The number of grids for each class will be determined by subtracting the previous year’s champion team of each class and the teams specified by STO and the organizer from the maximum number of available grids. The above method of calculation will be applied in conjunction with the proportional distribution ratio set by the organizer. Under the above-mentioned calculation, if the number of cars are less than the numbers decided by organizer, there will be filling-up of grids within the class concerned under the approval of the Panel of Stewards.

④ If vacancy of grids still remain even after the above method was taken, the filling up of such grids will be made among the teams qualifying time recorded.

Filling-up of the remaining grids will be made in the order of best qualifying lap time (combined time of Driver A and Driver B) and such grids will be established at the back of the grids.  Super Taikyu Series does not apply “reserve” driver for the race who satisfied the standard time of qualifying but grids were not established because of the limited number of grids. (9) When red flag was displayed to interrupt during qualifying session, overtaking is forbidden and all the cars must return to pits immediately and must stop the engine. All the work including refueling is allowed in the pits. Competitors shall wait for the instructions from the officials if the race will be resumed or will be finished after red flag. (10) For a round with no qualifying practice, a way of establishing starting grids can be found in the Supplementary Regulations. (11) In the event the number of qualified cars did not occupy all the starting grid, drivers who failed to achieve the standard qualifying lap time or drivers whose qualifying lap time was cancelled by penalty can submit a petition to compete in the race attached with the reference from STO to the Panel of Stewards. . Based on the requests from the competitors, the Panel of Stewards may allow the participation of the drivers (teams) in the race. However the following conditions must be met: Cars originally qualified in the qualifying rounds must not be excluded.  The drivers (teams) who submitted the petition must be judged that they are capable of achieving the qualifying standard lap time. Those drivers (teams) must guarantee for all safety matters. (The petition must be submitted to the secretariat office within 30 minutes after the announcement of the provisional results or after the notification of the cancellation of the results.) (12) Notwithstanding the regulations above, the final decision related to the starting grids for both qualifying and races will be decided by the Panel of Stewards

If the clerk of the course decides it is necessary for safety reasons, he/she can declare a Full-Course Yellow “FCY”. Under “FCY,” all cars must line up in single file and no overtaking is allowed. Waving yellow flags with “FCY” board will be displayed at all observation posts. While “FCY” is under operation, the cars deliberately slow, the cars with unstable driving or the behavior that might cause danger for other drivers will be reported to the Panel of Stewards. This is applicable to all the cars on the course, the pit entry and the pit lane exist. 2. During FCY, all the cars shall not go back to the pit. 60 seconds or more penalty stop will be imposed on the offender. 3. Double yellow flags must be waved and “ZONE 50” board must be displayed at the observation post just before an incident has occurred where it is dangerous and the marshals are working on clearing the area. Once the flags and the board were displayed, the drivers must immediately reduce the speed to 50km/h.

After passing “ZONE 50”, the restricted “ZONE 50” will be released at the post where a waving yellow flag with “FCY” board displayed but overtaking is forbidden. There is a case that “ZONE 50” area may be more than one areas . 4. Once the problem is solved, the clerk of the course declares the release of “FCY.” At this point, all the posts remove the yellow flags and “FCY” boards and at the same time green flag is waved. The race as well as overtaking may be resumed with no restriction regardless of positions between cars nor the location of cars towards racing line. 5. There may be intervention by safety car after the end of “FCY” period, in the event the problem has not been solved and still safety issues remained. 6. During “FCY”, only drivers who were in pit entry to carry out their penalties (e.g. drive-through and penalty stops) can consume their penalties. 7. Race operation other than what is stated above will be notified in the Supplementary Regulations or on the official notice. [Appendix 2] Safety Car (SC) operation during the Race (Management in Accordance with the Appendix H of the FIA International Sporting Code) 1.

When the order is given to deploy the safety car, waved yellow flags and “SC” boards will be displayed at each marshal post and at the signaling tower for the duration of intervention. 3. The safety car will join the track immediately from the pit exit with its orange lights illuminated and will do so regardless of where the leading car is located. 4. All competing cars must form up in line behind safety car no more than 5 car lengths. 5. With the exception of the cases listed under, no driver may overtake another car on the track until safety car returned to the pit and the car reached the start line. The exceptions are:

 If a driver is signaled to do so from the safety car.  Any car stopping in its designated garage area whilst the safety car is using the pit lane

 If any car slow down with having an obvious problem. 6. Cars must not drive unnecessarily slow down, drive erratically or in a manner which could be deemed potentially dangerous to other drivers whilst safety car is deployed. 7. When ordered by the clerk of the course, the driver in safety car will use green light to signal to any cars between the safety car and the leading car to instruct that they should pass safety car to take up the back of the file. These cars will continue at reduced speed and without overtaking until they reach the file of cars behind the safety car. 8. The safety car shall be continued at least until the leading car is behind cars comes behind the safety car and all remaining cars are lined up. After lined up behind the safety car completed, the leading car must keep within 5-car length (excluding the case of restart of a race). Between each car of the line of the remaining cars must keep as close as possible. 9. When the leading car behind the safety entered the pit, the car right behind the safety car will be a leading car. The leading car returned to the pit will not be positioned behind the safety car again 10. While a safety car is deployed, the competing cars are allowed to enter the pit lane. However, in exceptional case where pit-in is restricted in a race, its detailed procedure will be notified in the Supplementary Regulations. The car entered the pit and the car on which any works are taking place inside pit during the safety is deployed are allowed to enter the track when the green light is turned on. (Red light remains illuminated from when the safety car is identified at the last corner until the last car of the line passed pit exit. During the red lights illuminated, any car in the pit lane is not allowed to enter the track.) 11. When the clerk of the course decides to call in the safety car, the safety car switched off the orange light and enter the pit road at the time the lap concerned is completed.

12. In order to avoid the likelihood of accidents before the safety car returns to the pits, from the point at which the lights on the safety car turned out drivers must proceed at a pace which involves no erratic acceleration or braking nor any other manoeuver which is likely to endanger other drivers or impede the restart. All the cars must keep the file with steady speed without overtaking. 13. As the safety car is pulled off from the track via pit-in road, the yellow flags and SC boards will be withdrawn and replaced by waved green flag. When the cars in line is passing main straight, green lights will be illuminated. Overtaking is forbidden until the car passed the start line (it will be control line depending on the track). Red lights at the pit exit keep illuminating from when the cars in line came to the last corner until the last car in line passed the pit exit and during this period the cars in the pit lane are not allowed to enter the track.

14. Each lap completed while the safety car is deployed will be counted as a race lap. 15. If the safety car is still deployed at the beginning of the last lap or deployed during the last lap, the safety car will enter the pit lane at the end of the lap and the cars will take the checkered flag as normal without overtaking.

16. Start of race behind safety car Under certain circumstances the race may be started behind the safety car. In either case, the orange light of the safety car will be illuminated at any moment before “one- minute” signal is shown. This is he signal to the drivers that the race will be started behind safety car. When the green lights are illuminated the safety car will leave the grid and all drivers must follow in grid order, no more than 5 car lengths apart. There will be no formation lap and the race starts when the green lights illuminated. Overtaking is allowed when a car is delayed when leaving the grid and cars behind cannot avoid passing it without unduly delaying. When the last car of the field behind the safety car has passed the end of the pit lane, green lights are illuminated at the pit exit. At this point the cars on the pit lane are allowed to enter the track and join at the back of the field lined up behind the safety car.

Any driver delayed and who is unable to re-establish the original starting order during the safety car is deployed, overtaking by such cars is not allowed and must take up the back of the field lined up behind the safety car. If there is more than one driver delayed, they must take up the back of the field after leaving their grids.
