"I was looking to start racing in the UK and wanted a good platform for sponsors. I like the Carrera Cup cars," said Breslin, who has previously only raced once in Britain, which was at Brands Hatch back in 2005. He recently tested with Team Parker Racing at Silverstone and will now tackle the pair of races on the National circuit, competing in the pro-am1 category.Meanwhile, joining the Apex Tubulars/Qserv squad for the Silverstone weekend will be Alasdair McCaig, racing alongside Tommy Dreelan in the team's pro-am2 cars.

He earns his prize drive weekend in the PCGB pro-am2 Carrera Cup car as part of the support given to Porsche Club GB Motorsport.The debut of this quartet of drivers will mean that 40 drivers will have raced in the 2008 Carrera Cup GB by the Silverstone weekend.
