Junior single-seater drivers Antonio Giovinazzi and Sean Gelael were victorious on their prototype racing debut, claiming the overall win in the three-hour Asian Le Mans Series race at Buriram.
The duo saw off three other LMP2 squads to give their Eurasia squad its first win of the season.
Gelael, who had secured pole in qualifying, suffered a puncture in his stint and dropped back, but eventually recovered to the top spot.
The Indonesian then handed the car over to Giovinazzi, who established a gap of more than 30 seconds by the chequered flag.
Giovinazzi and Gelael have been long-time teammates in junior single-seaters, pairing up in the 2012 Formula Masters China season and the 2013-14 European Formula 3 campaigns.
The latter spent 2015 in Formula Renault 3.5 and is set for a GP2 switch with Campos, while Giovinazzi's plans for this year remain uncertain.
