After a mid-season break, the 2005 Michelin Porsche Club Championship bursts back into action with a double-header at Thruxton over the weekend of 20/21 August.Heading into the final six races of the season, Ian White is firmly on target for his goal of 2005; the overall championship title. Having missed it narrowly in 2004, the Somerset racer is even more determined to make 2005 his year in the 3.2 Carrera.Thruxton, which is one of the fastest tracks on the calendar, presents a big challenge to the Porsche racers and this rare visit to the Hampshire track could be pivotal in the outcome of the 2005 title contest. It is pretty much home ground for White, and he will be using his skill and bravado to maximum effect around the high-speed sweeps.However, in recent races, White has faced a big challenge from the similar car of young Andy Purdie. Wins at Donington and Rockingham mean that the Kent-based student has now won three of the last four races, but Thruxton is another new track for him to master.Another young charger is Lewis Tootell (968CS) and, like Purdie, he will be learning about Thruxton but his form to date suggests that he learns fast! Mark Lillington is another rapid 968CS pilot, while Kevin Harrison (968CS) deserves a change in fortune after a trying season.Four drivers have emerged at the head of the very open and high competitive class two, with Marcus Carniel belying his limited experience to hold the points lead after the Rockingham double-header in his 911SC. He is another driver new to Thruxton.Tom Segrue (944 S2) and Colin Ingram (911SC) are both well in contention and Segrue has more Thruxton experience than his rivals. David Botterill is chasing hard in his 924 Carrera GT, the only example of the model currently racing in the UK, while Frazer Robertson has bounced back into contention in his 944S2 with some mighty form over recent races.The 911SC of Ben Demetriou is now clear at the head of class three, with Chris Stewart (911E) leading the chase.
