Sam Hancock claimed victory in a thrilling round 16 of the Porsche Carrera Cup GB at Knockhill today (Sunday 17 August 2008) as Tim Bridgman battled through to second place on the last lap. On an action-packed final lap, Tim Harvey took third to close to within just three points of Michael Caine in the championship race.It was also dramatic in the pro-am1 category as Tony Gilham beat Nigel Rice, but only after both had spun through the gravel after a clash at Seat Curve. Meanwhile, Rory Butcher drove another fine race in the PCGB entry to complete a double in the pro-am2 category and finish fifth overall.This time around, Hancock (Jota Sport) was able to convert his pole position into a first lap lead and he was never headed again, but there was plenty going on in his mirrors, with Caine (Team Parker Racing) as a constant shadow. "You can't rest for a moment round here," said Hancock, who found himself coming under increasing pressure from Caine heading into the closing stages. "I was having some brake balance issues and I just wanted to get a small margin," said Hancock after taking victory. "To come away from the weekend with two poles, a second and a win is great."However, it all went awry for Caine on the final lap. He had been battling against a soft brake pedal and Tim Bridgman (Team Parker Racing) was getting closer and closer having earlier battled ahead of Harvey (Red Line Racing). Into Carlube Corner with less than half a lap to go, Caine's brake problem came to a head and he ran wide as Bridgman dived through. Then, at the final hairpin, Harvey dived inside Caine and Caine's can spun as they touched. "Michael made a mistake and I had to go for it," said Harvey. But the time he rejoined, Caine was down to sixth behind Phil Quaife (Jota Sport) and Butcher."I was just running out of brakes," said a frustrated Caine, having seen his nine-point championship lead over Harvey drop to three points over the course of the weekend. Bridgman, having started fifth on the grid, was elated to have fought through to second. "I'm really, really happy with that," said Bridgman.The battle between Gilham (ReDesign Racing) and Rice (Red Line Racing) raged all race and came to a head as they battled side-by-side into Seat Curve with three laps to go. The cars touched and both spun into the gravel and it was Gilham who managed to get back onto the track first to make certain of victory. "I just tried to keep it spinning through the gravel. That was hard work," said Gilham.Behind Butcher in pro-am2, Glynn Geddie (Parr Motorsport/Apex) drove a measured race to take second as Graeme Mundy (RSS Performance) battled through to third place.
