In a shift in focus, Nissan North America have decided to allocate more resources towards the Pirelli World Challenge, abandoning the IMSA-sanctioned Continental Tire SportsCar Challenge (CTSCC) in the process.

They've been backing Doran Racing for the past four seasons in the CTSCC. Nic Hammann, Steve Doherty Nick McMillen, BJ Zacharias, Brad Jaeger, and Bryan Heitkotter all made starts for the team this past year.

“Nissan North America is consolidating its motorsports presence to showcase the Nissan GT-R in the Pirelli World Challenge GT category for the 2016 season," a statement read.

“Nissan will continue to support grassroots motorsports efforts in SCCA, NASA and other organizations, as well as continue to retail performance and motorsports components through its Nissan Motorsports Competition Parts arm.

“Nissan wishes to thank Doran Racing for four excellent seasons of competitive racing with the 370Z and also IMSA for their support of road racing in North America.”
