With just three races remaining in the British GT Championship Matthew Allison's confidence in being crowned the GTC champion is high after taking his fourth category victory.

The Norwich racer and co-driver Jonny Lang could hardly complain about their performances' at Rockingham Speedway as the pair will travel to the next two races at Brands Hatch with a six point advantage over Ryan Hooker.

"It's possible to win it at Brands," explained Allison. "If Jonny and I finish on the podium in both races, ahead of Hooker, then its our's without the worry of the final race at Silverstone, which, at two hours, is twice as long as normal."

Lang qualified the Trackspeed-prepared Porsche 996 GT3 in second place for the opening race with Allison claiming pole position for race two.

"We thought we might struggle," said Allison. "We didn't expect to be on pole because we are carrying full success ballast. It's like having a slightly overweight passenger sitting beside you."

In the opening race Lang held station behind Hooker in second place and exchanged early with the local racer, who put in some storming laps.

They paid off as he was left with a slender lead when Hooker swapped with Phil Keen.

"I couldn't relax as Keen kept the pressure on but by the finish I had worked up a 10 second cushion," added Allison.

Overnight the Porsche was checked over and a gearbox oil leak was found which meant fitting an inferior replacement, with gear ratios which didn't suit the tight nature of the circuit.

Nevertheless, in race two, Allison kept the car in the podium places and handed it over in third to Lang, who was unlucky to fall back to fifth place in the final few laps.

With Hooker in second place their overnight lead had shrunk by three points, but it could have been worse if the team hadn't spotted the oil leak.

Carlton Rode's Gavan Kershaw showed just how good the Lotus Sport Cadena Exige GT3 sportscar is by qualifying the Norfolk-built machine fastest in category and third overall at Rockingham.

In the early laps of race one Kershaw had several energetic battles with faster cars but held third place overall before handing over to Barrie Whight, who suffered a late puncture but was still able to limp in fourth in class.
