20. Mandatory Pit Stops

20.1.

A minimum pit stop time will be imposed for GT Challenge Asia, GTC/GT2 and GT4 Asia. The pit stop time will be issued in a Bulletin from the Stewards. Any car whose pit stop time is less than the given time between pit in and pit out will be given a penalty by the Stewards of the Meeting.

For each car, the minimum pit stop time will be adjusted according to the penalties laid down in articles 16.8 and 16.9.

20.2. Case A - for Competitions with two one-hour races.

a) A mandatory pit stop for changing drivers is to be carried out during each of the races. The car must cross the pit entry line from 25:00:00 after the Official start of the race until 34:59.99 after the Official start of the race. Only one driver change may take place during the race. Any pit stops taken before the start of the pit window will not count as the mandatory pit stop.

b) The pit stop will be of a controlled duration (Mandatory Pit Stop Time). Before the start of the meeting all competitors will be notified of the Mandatory Pit Stop Time by Bulletin. Timing for the pit stop begins when the car triggers the timing loop at the pit lane entry. The stop is considered to be complete when the car triggers the timing loop at the pit lane exit.

c) For single-driver cars according to Article 13.1.3, an additional minimum pit stop time may be applied. If applicable, this time will be published in a Bulletin from the Stewards of the Meeting at each event.

d) If a driver does not make their obligatory pit stop for the driver change within the mandatory pit stop window, the team will have to perform a Stop and Go Penalty. If it is impossible for this stop and go to take place during the race, a time penalty will be added to the car's race time.

e) If a Full Course Yellow procedure is in operation, or the Safety Car is on track at the time when the pit window is scheduled to open (25:00 after the start of the race) the race director may decide to delay the opening of the pit window. Teams will be notified of any such delay in advance. Should a Full Course Yellow period be declared, or should the Safety Car be called on track, during the pit window, the race director may extend the time of the pit window by a time between one and three minutes.
