The Porsche Carrera Cup GB switches to the home of British motor racing at Silverstone for the penultimate weekend of the season on 17/18 September for what could be the deciding races of the year.For the first time, the Carrera Cup racers will be in action on the 1.6-mile national circuit at Silverstone, which promises all-action racing as the championship heads towards a conclusion.Damien Faulkner (Team Parker Racing) is the man with one hand on the championship title and the road-going Porsche 911 Carrera that awaits the 2005 champion. Heading to Silverstone, the Irish ace has a 48-point lead over defending champion Richard Westbrook (Red Line Racing). To clinch the title at Silverstone, Faulkner must end the weekend with a 44-point lead over Westbrook as there will be another 43 points on offer in the final two races at Brands Hatch in early October. In the Carrera Cup, all rounds count so there are no confusing issues over dropped scores across the 20-race season.Faulkner knows he does not have to win races to seal the prestigious title, but he is a determined racer and does not want to cruise to the title. Equally, Westbrook has vowed to keep pushing and won't give up while there is still a glimmer of hope for his title bid. Faulkner has finished each one of the 16 races to date, but should he fail to finish a race at Silverstone the whole situation could be very different. A dominant double victory at Knockhill last time out proved that Westbrook is on top form.Of course, the Silverstone races are not just about Faulkner and Westbrook. Tim Harvey (Team RPM) and Jason Templeman (Team Parker Racing) are not just battling for third place in the points, they are also determined to score race wins and break the Westbrook/Faulkner grip on the top step of the podium this season.Heading for fifth place in the final points is Nigel Rice (Red Line Racing), but he will be chasing a podium finish at Silverstone as well as working to fend off team mates Stephen Shanly and Jason Young. Up with the Red Line trio in recent races has been Steve Clark (Team RPM), while series newcomer Paul Ip joins the action in the third car from Team RPM.Others to watch in the field include David Ashburn (Track Speed), Michael Corridan (Team Parker Racing) and Jim Geddie (Apex Tubular), who will make his Silverstone debut after an encouraging first Carrera Cup outing at Knockhill.Meanwhile, racing the Porsche Cars with Team Autosport entry will be young single-seater ace Scott Mansell, who will make his Porsche debut amid a season of racing in the USA. The Tamworth youngster has previously held the outright lap record at Silverstone in a former Grand Prix Benetton, so the Porsche 911 GT3 Cup will offer a rather different challenge!After qualifying on Saturday, both Carrera Cup races will be held on Sunday.
