Harry Burgoyne headed home a KMR Sport 1-2 in the final race of the weekend at Donington Park, as Kevin Mills' squad claimed the Teams' Championship title for the third year in a row.
Burgoyne started fourth on the grid, but blasted to first almost immediately with a blinding start to pass Nickolas Ellis, Megan Bruce and pole sitter Dan Hickey within seconds of the race start.
The young Scotsman romped away on the opening lap as battles developed behind him, with teammate Lucas Blakeley rising from eighth to fourth at the first corner, before going past Fox's Bruce exiting the Old Hairpin, and then dispatching Hickey on the approach to the Esses.
With clear air, Burgoyne had built a 2.2 second lead on the first lap, and 2.7s by the end of lap three. But Blakeley was clearly on a charge, and reduced the deficit to under a second within three laps.
The pair were nose to tail from there on, but Burgoyne seemingly had it covered and led his teammate home to secure a first win in GB4, and a KMR 1-2 at that.
The Gloucestershire squad needed to out score Elite Motorsport by 13 points heading into the event, and Fortec by 15 to wrap up the title with a whole round to spare, and the combined score for the top-two, including strong 'bonus' points for positions gained meant they outscored their rivals by 18 and 20 points respectively.
Elite's Alisha Palmowski powered past Hickey to take the final spot on the podium, with Hickey's fourth place still being his best GB4 result, while KMR's Chloe Grant completed a great race for her team with a strong drive to fifth.
Fortec's championship leader Linus Granfors went from 10th on the grid to sixth ahead of Fox Motorsport's Branden Templeton, while Elite's Finn Harrison was hit with a track limits penalty mid-race and dropped to eighth in the final classification.
Elite's newcomer Ellis completed his first weekend with ninth while Arden's Leon Wilson completed the top-10.
