The #36 Toyota GR Supra shared by Sho Tsuboi and Ritomo Miyata was on course for at least second place until their charge was ended by a loose front left-wheel in the closing stages of what proved to be a weather-shortened curtain-raiser.
Miyata, who took over from Tsuboi as the track dried out following an earlier shower, led a queue of cars into the pits under caution to change back to wet tyres after another deluge hit the former Pacific Grand Prix venue.
