The local man got the jump at the lights, and headed team-mates Dan Rowbottom and Ash Sutton throughout for a Motorbase Performance Ford Focus ST 1-2-3.
Second and third positions swapped on the final lap, when Rowbottom allowed championship leader Sutton – who had also gained the point for fastest lap – into the runner-up position.
The three Fords were scarcely troubled. Cammish and front-row partner Rowbottom took the start on the soft Goodyear tyres, on a weekend where all three compounds must be used across the trio of races.
Sutton was on the medium tyres, and dived down the inside of Rowbottom at Tower on the second lap, only to run wide on exit and allow the bearded Midlander to reclaim the position at the Jim Clark Esses.
Sutton remained hard on the bumper of the sister Ford of Rowbottom until he gained the place on the final lap.
“I missed a load of gears on the last lap on the back straight; what can you do?” explained a tongue-in-cheek Rowbottom.
“It was a weird touring car race,” related Cammish. “Usually you’re in a battle so you’re looking forward to the end of the race, but that was a bit more sedate.
“I’m happy with races like that – I wish they were all like that…”
