Rounds 4 & 5: Snetterton, 17-18 May

The Calder clan ruled the roost in Norfolk as Colin Calder took back-to-back wins with daughter Heather shadowing him in second spot.

Third place on both days went to Terry Holmes, who got his championship assault back on track after failing to score at Lydden.

The two-litre brigade filled the next places on both days; Saturday saw Craig Sampson snatch fourth ahead of Mark Smith, while on Sunday Mark put the youngster down to fifth. Smith left Norfolk still leading the championship but with the Calders closing in.
