Josh Fisher scored his second victory of the Castle Combe FF1600 by Melksham Motor Spares after on-the-road winner Luke Cooper was given a five-second penalty for a track limit infringement.
Cooper came out on top of an intense battle with pole-man Fisher that lasted throughout the ten-lap sprint, the pair swapping the lead several times.
The decisive move for the lead came going onto the penultimate lap, as Fisher lost the back of his Van Diemen JL14 at the final corner and lost drive heading onto the straight.
Cooper then dove up the inside into Quarry, securing the lead and the on-the-road victory, but takes second following his penalty.
Chris Acton came out on top of a close battle for the final podium position, the Ray driver pipping Tom Hawkins to the place by just three-tenths of a second.
David Cobbold took fifth in his Van Diemen RF89 ahead of recovering double Castle Combe FF champion Adam Higgins, who managed to drag his Firman 17 machine into sixth from 18th on the grid.
Felix Fisher looked set to make it a three-way battle for the win in the early stages, but hit mechanical trouble and was forced to pull into the pits and retire.
Paul Mason again took the spoils in Class B by taking 11th overall, while Steve Bracegirdle and Alan Slater took Classes C and D wins in their Van Diemen RF89 and Nike Mk4s respectively.
