It took exactly 44 years for Rod Birley to clock up 600 race and class victories as the Kent racer reached the milestone at Snetterton on Saturday – having started the ball rolling at Cadwell Park in 1973.

This time Birley used his potent Ford Escort WRC to triumph in the Quaife Modified Saloons, having first tasted success in a humble Hillman Imp, leading home Andy Banham.

Birley added another victory, and his 47th at the Norfolk venue, later in the day, with Banham much closer this time but unable to deny the multi-race winner.

Meanwhile, Lewis Smith claimed the overall honours in both of the combined races, with his Vauxhall Tigra leading the first throughout while displacing Steve Burrows from the lead in the reverse grid second encounter while Foulden's Ian Hales was a double retiree.

To cap a stunning weekend, Birley added two more class victories in the Cannons Tin Tops series on the Sunday as James Ross led both races from start to finish.

Suffolk's William Smith stood on the second step of the Caterham 420R podium on his debut in the category but was squeezed down to fifth place in race two as Lee Wiggins and Danny Winstanley took the honours.

A last-lap surge from James Beardwell secured him victory in the opening Caterham Seven 310R race, while Lee Bristow kept a tighter grip on the second race repelling all attempts to unseat him.

Daniel Quintero and Alan Cooper continually swapped the lead in the opening Caterham Seven 270R race with the former leading when it mattered at the chequered flag.

In race two Cooper led until the final laps when he found himself elbowed back to second place once more, this time by Russ Olivant.

Jay McCormack kept his nose in front every time the Caterham Roadsports field crossed the start and finish line in their opening race, but a stunning drive from a first-lap sixth place secured Peter Spencer victory in the second event.

Mark Abbott profited from Richard Wise's last lap problem in the opening OSS Sportscar race but in the following two encounters Wise wasn't to be denied victory.
