Super GT

New Zealander Nick Cassidy and Japanese driver Ryo Hirakawa have been crowned 2017 Super GT champions after finishing second in the final race of the season at Motegi.

Cassidy/Hirakawa came into the weekend in the points lead, with a second placing good enough to guarantee the leading GT500 class title.

They qualified the #37 KeePer TOM’S Lexus LC500 in third position, with Cassidy getting past the #6 Team LeMans Lexus LC500 on Lap 4.

The #23 Motul Nissan GT-R of Ronnie Quintarelli and Tsugio Matsuda comfortably won the race from pole position despite damaging bodywork when the Italian hit the #6 Lexus on the formation lap.

That result meant that Hirakawa had to bring the #37 Lexus home in second position, and while he crossed the finish line 6.2s adrift of the #23 Nissan, he was also 7.1s ahead of third position at the end.

Yuji Tachikawa/Hiroaki Ishiura (#38 Zent Lexus LC 500) completed the outright and GT500 podium.

Cassidy’s and Hirakwa’s triumph makes the two 23-year-olds the youngest Super GT champions.

“As Hirakawa-san just said, all I can say is that I am relieved,” said Cassidy.

“This is only my second season in GT500 but the team has put their trust in me, so I worked hard to live up to that trust.

“All year it was a season of holding back when we needed to hold back and pushing hard when we needed to push.

“Today it was a race where we needed to conserve, but it went well and was a good race.”

In GT300, New Zealander Jono Lester and Kyosuke Mineo finished fourth in class, while Australian Jake Parsons and Shinnosuke Yamada were 14th after fighting back from an early drive-through.
