Connor Jupp and Darius Karbaley both scored maiden victories in the MSA British Cadet Championship at Glan Y Gors but it was Nathan Aston who left North Wales as the championship leader.
Rounds five and six of the Formula Kart Stars run MSA Cadet Championship took the drivers to the beautiful foothills of the Snowdonia mountain range and the rolling 1100-metre Glan Y Gors circuit.
Despite its challenging nature, the relatively remote location of the track meant that few of the drivers arrived for the weekend with bundles of test and race data, which in turn led to some surprising results as the weekend wore on.
On a warm sunny Saturday Aston set the pace in timed qualifying ahead of Daniel Ticktum and Luke Barker but all three were locked out of the winners circle in the heats as Jupp, Karbaley, championship leader Tom Harvey and recently crowned O-Plate winner Lando Norris took the honours.
All four races were decided by less than four tenths of a second with the sweeping nature of the circuit lending itself to some excellent racing.
Thanks to a win and a second place in his heats Harvey took pole position for the final with his Fusion Motorsport teammate Karbaley alongside him. But as a pulsating race progressed it became clear that Jupp, from grid four, and Aston from grid five were the ones to beat.
Jupp led into the final lap with Aston on his bumper and as the two entered the Carousel Aston forged through. But Jupp wasn't defeated yet and got alongside his rival as they ran through the downhill sweepers towards the finishing line. Into the final corner Jupp made the best exit and crossed the line just seven hundredths ahead of Aston for his, and his Eclipse Motorsport team's first British Championship win.
Harvey took third from Karbaley, Rory Cuff and American driver Santino Ferrucci.
Saturday's pleasant conditions gave way to wind and rain for much of Sunday with qualifying taking place on a greasy track with the heats taking place in even worse conditions before the track dried for the finals.
Cuff was fastest in qualifying just ahead of qualifying expert Barker, Aston and Shanaka Clay but when the heats began it was the usual suspects at the head of the field with Jupp, Aston and Karbaley (twice) taking the wins.
After a dominant drive in his second heat Karbaley chased Aston away from the start of the final and the race soon became a two kart dice. Driving with great maturity Karbaley sat on Aston's rear bumper for the first 18 and three quarter laps of the 19 lap final until, approaching the final corner he made his move. Forcing Aston to defend Karbaley took a wide line into the last turn which gave him a much better exit and in a classic drag race; he was able to pip his teammate to the chequered flag.
After being beaten on the last lap twice in two days Aston Was understandably disappointed but with Harvey only finishing sixth behind Norris, Jupp and Cuff Aston regains the championship lead he last held at the end of the opening two rounds of the championship at Rowrah.
