Dan Wheeler moved to within two points of the championship lead following his fifth podium finish of the season at Thruxton.
Having never driven the circuit before, Wheeler put his Mini in fourth place in qualifying, and leapt into second by the second lap of race one.
However, his progress was dented when he came together with James Coulson, sending the MK man spinning off into the grass.
He rejoined the pack in eighth and in the closing laps improved his position to cross the line fifth.
Wheeler lined up alongside title rival Kane Astin for race two, with Rupert Deeth on pole and Coulson ahead.
It would be a three-way battle for victory, with Deeth, Astin and Wheeler all vying for position and vital championship points throughout the ten-lap race, continuously swapping places. As they entered the last corner, Wheeler had the lead and the finish line in his sights.
However, Astin made a last-minute lunge and in the process straight-lined the chicane.
Astin claimed the win with Wheeler second, his fifth podium of the season, with Deeth third.
“It was a slightly disappointing weekend in terms of results, especially being so close to another win in the second race,” said Wheeler, managing director of Milton Keynes-based clothing company Dread. “However, we’re at the midpoint in the season and I’m running second in the championship. There’s plenty of time to take the lead.”
