Liam Griffin is the latest driver to step up to the 2009 Porsche Carrera Cup GB and he will join the Motorbase Performance team for the next two races at Silverstone (29/30 August).Griffin only started racing at the beginning of 2008, but has already made a big impression in the VW Cup, taking three poles and two wins to date this season. He now wants to consider the Carrera Cup GB for 2010 and will use the Silverstone weekend as a toe-in-the-water exercise."I've always been a car nut," said London-based Griffin. "Then in 2007 I got invited to a track day at Spa. It was a day driving Porsches and it was the best day I'd ever had," he said. "So I decided to go racing. I got my licence in February 2008 and did six rounds of the VW Cup; going from near the back to near the front."Griffin returned to the VW Cup this season and now has two race wins under his belt. "I've put a lot of effort in and I'm prepared to listen and learn. I drive a Porsche on the road and I'm a massive Porsche fan, so it's a boyhood dream to race one."After a recent test at Silverstone, with team mate Michael Caine offering guidance, Griffin decided to tackle a race weekend. "I've never raced a rear wheel drive car and the sequential gearbox was new to me, so I'd got a lot to learn. But by the end of the test day I was happy with the car. I'm not expecting miracles but I'll look to do next season in the Carrera Cup if all goes well."Griffin recognises that he faces a big challenge, but says that the championship structure of pro and pro-am1 categories is ideal for him. "The idea of being in exactly the same car as drivers like Tim Harvey and Michael Caine really appeals; you can measure yourself and it gives you something to aim at. I want to learn and get better."Team boss David Bartrum is delighted to have Griffin joining Caine and Ollie Jackson in the Motorbase Carrera Cup squad. "Liam is a very focused guy and he's very switched on. He's already working well with Michael Caine and our engineer Patrick de Groot," said Bartrum. "We'd love to work with him beyond Silverstone; he fits in very well with the team."
