Australian James Davison claimed a top six finish on his Pirelli World Challenge debut at the Circuit of the Americas.
The 28-year-old managed to bring home his AIM Autosport Nissan GT-R in sixth in Race 1 to claim 76 valuable points on his first start in the American GT3 category.
The Ferrari of Olivier Berretta took the overall honours just 1.6s ahead of Ryan Dalziel’s Porsche 911 GT3R, while Johnny O’Connell guided the new Cadillac Racing GT3 into third.
Factory McLaren driver Kevin Estre provided a wet weather driving masterclass as he dominated treacherous conditions to win Race 2 by more than half a minute.
Dalziel completed his strong start to the series with another second place finish ahead of Nick Catsburg’s Lamborghini Gallardo in third.
Set up issues blighted Davison’s hopes of another Top 10 as he finished a distant 16th.
The Pirelli World Challenge heads to St Petersburg for the second round on March 27-29.
