Kiwi V8 Supercars team Super Black Racing have pulled off a major coup signing exciting New Zealand driver Richie Stanaway for this year's endurance events.

The New Zealander earned his first race win for his new team and Holden's 500th victory in the sport at the high-speed circuit at Symmons Plains near Launceston.

Michael Caruso may be leading the V8 Supercars championship at the moment, but it's highly unlikely the Nissan Motorsport outfit will still be on top come tomorrow.

Kiwi Scott McLaughlin kept his Volvo out of trouble despite heavy rain and fuel stop dramas.
