It was announced on Saturday ahead of the first round of the season at Okayama that the #8 ARTA NSX-GT shared by Toshiki Oyu and Tomoki Nojiri would have to serve a five-second stop-and-go penalty during the race as a result of an authorised chassis change.
SUPER GT rules do not permit GT500 cars to change chassis except in cases of force majeure, such as after a major crash.
