A total of 10 cars participated of what marks the third group test of the year so far for GT500 cars, with all five Honda NSX-GTs joined by a quartet of Toyota GR Supras and a single Nissan Z.
The #17 Astemo-sponsored Real Honda of Koudai Tsukakoshi set the day's quickest time in the two-hour morning session of 1m16.263s, around a second faster than last year's pole time at Okayama, albeit in somewhat cooler and therefore faster conditions.
