Tim Harvey will bid to extend his unbeaten run in the 2010 Porsche Carrera Cup GB when the championship continues this weekend (1/2 May) on the Grand Prix circuit at Brands Hatch.Harvey, lead driver for Red Line Racing, has won all four races to date to take an early 12-point lead in the championship and reckons he's never had such a good start to a racing season during his 28-year career."Without a doubt it's the best start to a season I've ever had," said the Oxford-based racer. "It's been almost the perfect start. Apart from the point for fastest lap in three races, I've got a maximum score. It may look easy from a results point of view, but it isn’t easy and we've worked very hard. But that makes it even more satisfying."Harvey is the most successful driver in the eight-year history of the Carrera Cup GB and has now contested 128 Carrera Cup races, winning 28 of them and taking a podium finish in another 63."Winning is infectious and you get used to it," said Harvey. "I'll try and keep it going as long as I can. I'm very comfortable in the car and I'm very happy with my driving this year; I think it’s better than it has been for a while. It's rare that I start the season at this level and it does make a difference. I done quite a lot of competition on two wheels over the winter, as I usually do, but I think I've come into the season sharper and fitter."Now comes one of his favourite tracks, the stunning Grand Prix circuit at Brands Hatch. "Brands Hatch GP is a wonderful circuit and a real favourite of mine," said Harvey. "I grew up around Brands and I've stood all round the circuit as a small boy in shorts watc
