Rounds 3 & 4: Ingliston, 30 April-1 May

Stewart Robb Snr and Colin Calder scored a run-off win apiece at Ingliston.

Robb Snr took a comfortable win in the first run-off ahead of Calder, who grabbed second place from Mark Smith’s grasp. Championship sponsor Steve Broughton was fourth ahead of the returning Colin Birkbeck and a determined Mike Musson.

Drama unfolded on Sunday when Robb Snr was eliminated during qualifying after his Pilbeam slewed off the track due to a broken rear suspension arm. With no spare on site the Championship leader was out, leaving Calder to cruise to his maiden Championship victory.
