The 964 C2s dominated at Oulton Park, championship returnee Marcus Carniel taking an early lead before Ian White moved ahead to take the win in the 30-minute race. The ever-rapid Brian Robinson came through for second ahead of Mark McAleer, Sarah Bennett-Baggs taking her second Class Three win of the season.
The Class Two Club runners shared the track with the Porsche Open field, Mike Clapham taking the win there ahead of Fraser Robertson.
QualifyingWhite was on pole after Saturday morning's qualifying session, Carniel taking up the other front row slot in his first run in his new 964 C2.
"I love this circuit," said White. "It's very busy and you can't relax for a moment, but it's great to drive in these cars."
Behind the lead two were the quickest of the 968 CS runners, Brian Robinson heading Ben Demetriou, Gary Duckman and points leader Mark McAleer. Dave Roberts headed the Class Three runners in his 944, 16th overall.
Race OneCarniel made the best of the start for his first race in his new mount, holding off White who was briefly on the grass through Old Hall. Demetriou was third, with McAleer into fourth and setting an early fastest lap in his chase of the leaders.
On lap two White looked outside Carniel into Old Hall, then went past going into Cascades, Carniel losing ground on the rest. Demetriou moved into second, but McAleer was closing in, and went past at Old Hall on lap seven after trying a move there the lap before.
White survived a brief out of shape moment at Knickerbrook on lap eight to stay clear at the front, while Robinson was finding his pace and went past Demetriou and set fastest lap in his pursuit of McAleer, who lost ground on oil put down by early Class Three leader Roberts, who retired trailing smoke.
Robinson took second, with McAleer third and Demetriou took fourth despite slowing at the end with a fuel problem.
"This is such a technical track, it has everything, but for once I didn't make a good start," said White. "I had a tussle with Marcus, then the oil made things hard, the car was squirming under me, but my gap was decent and I held on."
"This is a superb driving circuit," said Robinson, "and there is life in the old dog yet! The car was going really well, I was running out of brakes but that was my only problem."
"I got a good start said McAleer, "I think I could have held second but I went off on someone's oil down at Cascades. Ben was quick today, and Brian was too far ahead, but it's points in the bag.""
In Class Three Bennett-Baggs had been battling with Roberts for the class lead, and his demise saw her left clear of the closing Adrian Stock.
"There were places where I could catch Dave," said Bennett-Baggs, "then I made a mistake out of Lodge and he got away. I was trying to put pressure on him, then I could see his car smoking, I'm surprising myself, that's two wins on the trot."
The Class Two runners had a fine race at the end of the day, Fraser Robertson taking the early lead ahead of Trevor Lewis. Clapham soon found his pace and worked his way to the front, leading from lap five onwards.
"That wasn't an easy race," said Clapham. "Fraser kept coming back at me, and the Open guys were quicker than us on the straights, but some were slower in the corners. It could be the luck of the draw where they caught you."
