Trent Hindman and Riccardo Agostini sealed the Lamborghini Super Trofeo World Final crown with fifth place in the second Pro and Pro-Am race at Imola.
Raphael Abbate and Yuki Nemoto won the race by 7.474-seconds from first-stint leaders Rik Breukers and Axcil Jefferies, after Super Trofeo Europe championship-winning pairing Mikael Grenier and Loris Spinelli lost second on-the-road thanks to a 20s time penalty.
Had the duo finished second, they would have won the World Final, but Grenier's seventh-lap clash with Jonathan Cecotto at Tosa meant they spent the second half of the race knowing there would be a penalty, which eventually dropped them to seventh overall.
Breukers led the first stint from pole position with Abbate chasing him, but shortly after they had stopped to hand over to their co-drivers, Nemoto passed Jefferies for the de facto race lead at Tamburello.
Once the pit-stops were complete and Nemoto had cycled back into the lead, he built a comfortable lead to the chequered flag, but the victory was only good enough to secure second in the World Final.
Spinelli and Dennis Lind followed Nemoto past Jefferies. But Lind retired after being forced onto the grass on the run out of Tosa by Spinelli, where he slapped the wall.
This, combined with Spinelli's time penalty, allowed Jefferies to finish second.
Richard Antinucci, sharing with Patrick Kujala, held off Kai Cozzolino for third place, the latter passing Agostini in the closing stages.
Agostini was a comfortable fifth ahead of Jeron Mul, sharing with Austin Versteeg, ahead of Spinelli after spending a frustrating first stint stuck behind Kujala.
Toby Sowery had run as high as second after a battling first stint before handing over to Artur Janosz, but the duo ended up 10th behind Jan Kisiel and Morgan Haber after a clash with Cozzolino.
Nicolas Gomar and Lucas Mauron won the Pro-Am class in 11th place ahead of Niels Lagrange and Pieter Vanneste.
But Edoardo Piscopo's last-lap pass on Kelvin Snoeks ensured he and team-mate Taylor Proto, who lost ground with an early spin, won the Pro-Am class of the World final overall.
