Michael Caine scored an epic victory in an enthralling round 13 of the 2009 Porsche Carrera Cup GB at Knockhill today (Sunday 16 August 2009).

The race was all about tyre choice on a wet but drying track and Caine's choice of slicks paid massive dividends as the race progressed. Through to a magnificent second overall and pro-am1 victory came Glynn Geddie, while Glenn McMenamin bagged pro-am2 after a hectic race.

As the race start approached the rain cleared and the track began to dry. But the field was split on tyre choice and title contenders Tim Bridgman (Team Parker Racing) and Tim Harvey (Red Line Racing) both opted for wets as they continued their battle for the overall title.

However, Caine (Motorbase Performance) was third on the grid and gambled on slicks, along with Geddie (Team Parker Racing), Robert Lawson (JHR), Charles Bateman (Team Parker Racing) and pro-am2 front-runners McMenamin (Parr Motorsport), Paul Hogarth (IN2Racing) and Bob Lyons (Celtic Motorsport)

Initially, with Caine making a cautious start as he waited for his slicks to come up to temperature, the leading trio of Bridgman, Harvey and James Sutton (Red Line Racing) went a long way clear. But as early as lap four it was clear that slicks had been the right choice and Caine quickly started to recover ground. By lap 14, Caine swept through into the lead and soon pulled well clear, leaving Bridgman and Harvey to face a rapid fall down the order as the track continued to dry over the second half of the race. Such was his advantage over Bridgman and Harvey that Caine was able to lap them in the later stages as they dropped to sixth and seventh at the flag. "I had to get heat into the tyres at the start," said Caine. "For a couple of laps I wasn't sure and it was a complete lottery. But there was no point being on the same tyres; you've got to be different. This time it worked for us!"

While Caine went clear, Geddie and Lawson led the chase as they worked through to second and third overall and battled for pro-am1 victory. They had both driven fine races, coping well on slicks in the early laps before capitalising on their tyre choice. "It was brilliant," said Geddie after his best result to date on his home track. "All we really wanted this season was to get in the top three," he said. Lawson, meanwhile, was frustrated to have lost the pro-am1 lead to Geddie in early traffic. "It was a close call; I was just disappointed with the traffic," said Lawson. Through to fourth and fifth in a race full of overtaking came Charles Bateman (Team Parker Racing) and Ollie Jackson (Motorbase Performance), with Bateman challenging Lawson at the flag and Jackson completing the pro-am1 podium. The contest in pro-am2 was just as dramatic, with McMenamin having to drive the race of his life to battle ahead of Hogarth as Lyons hunted them down in third place. After a race-long battle, less than a fifth of a second decided the result after McMenamin tigered ahead of Hogarth at the hairpin. George Brewster went off like a scalded cat," said McMenamin of the Celtic Speed car on wets in the early laps. "Then I saw him in the distance," added McMenamin before moving ahead with Hogarth in pursuit. "I'm just so chuffed; I can't believe the result," said McMenamin
