Tommy Dreelan and George Brewster will both contest full seasons in the Porsche Carrera Cup GB, racing alongside young gun Rory Butcher in the three-car squad from Celtic Speed. With all three drivers from north of the border and the team based in Montrose and headed by Scot Alan Keith, this is a strongly Scottish team.Both Dreelan and Brewster have competed in the Carrera Cup GB since the middle of 2009 and will chase the Pro-Am2 title this season. In 2010, Brewster was one of the title contenders in the category and missed the title by just two points after a very strong and consistent season.Aberdeen-based Dreelan, who originally hailed from Ireland, only started racing late in 2005 and has since raced extensively in Porsches. Edinburgh’s Brewster, meanwhile, raced karts as a youngster and then returned to the sport a decade ago, racing first Caterhams and then Porsches.“We’re looking forward to a full season in the Carrera Cup,” said Dreelan. “With Rory in the team we’ve got someone to chase now and that should be a big help with the data as well.”The Celtic Speed team is busy testing the latest 450bhp 911GT3 Cup cars and will take part in the pre-season test and media day at Snetterton on 22 March. The opening two races of the season will be at Brands Hatch over the weekend of 2/3 April.
