Stephenson to join Carrera Cup GB at Oulton ParkMark Stephenson will join the Porsche Carrera Cup GB at Oulton Park on 23/24 June and plans to complete the season in his Globewatch-backed car.Stephenson's car will be prepared by ABG Motorsport as the Cheshire driver enters his third season of racing. After starting in the Porsche Open in 2005, he contested a full season last year and finished runner-up to Peter Morris in the competition for 911GT3 Cup cars.Now, equipped with the latest 911GT3 Cup car, Stephenson is moving up to the Carrera Cup and knows that he faces a major challenge. Prior to starting racing in 2005, the company boss had only taken part in track days. "I'd never raced anything before the 2005 season," he said.Stephenson, from Manley in Cheshire, is making a later start to his Carrera Cup campaign than expected after the car was damaged earlier in the season."The car will be ready for Oulton and I want to do a couple of tests before the weekend. Oulton is my home track and I now hope to finish the Carrera Cup season. It's been a bit of a bad start to my season, but I was really getting to grips with the car before the accident."
