Adam Carroll made the perfect start to the British GT championship, by winning the opening round of the series at Oulton Park.
Sharing an FF Corse Ferrari 458 with England's Gary Eastwood, the former A1 GP champion from Portadown fought off stiff competition in the final laps to win from the Oman Racing Aston Martin of Liam Griffin and Rory Butcher.
Carroll secured a one-second victory with the fastest lap of the race on the final lap.
Fellow Ulsterman Andrew Watson, making his debut for the Von Ryan McLaren team, had been an impressive second early in the race but crashed out.
Meanwhile, Colin Turkington is sixth in the British Touring Car standings after the opening series of races at Brands Hatch.
The defending champion, now with the BMR Volkswagen team, had an up-and-down day with fifth place in race one, third in race two and then a lowly 12th after spinning off in race three.
There were three different winners, Rob Collard for Turkington's old BMW team as well as the Honda duo of Gordon Shedden and Matt Neal, who leads the series.
Jonny McMullan is second in the BSRCC Formula Ford championship after the first two rounds at Silverstone. He was fourth in race one and second in race two with Joey Foster winning both.
Derek McGarrity has taken a stranglehold on the Northern Ireland Rally Championship after his victory in the Circuit of Ireland National Rally, and Sam Moffett is the new leader of the Irish Tarmac championship following his fourth place on the Circuit International.
