Yorkshire racers Nigel Moore and Jody Firth maintained their grip on the Avon Tyres British GT Championship GT4 Class after a victory at the Belgian circuit of Spa-Francorchamps.

Tockwith-based Moore, 17, and his 27-year-old driving partner Firth, from Wakefield, were in exceptional form in their Team WFR Ginetta G50 as they notched their third win in four races.

In race one, they were involved in a three-way battle for GT4 class honours, taking third after losing a lap when Firth spun off.

In the second race, the tussle for honours was as dramatic and exciting as ever, with Moore fighting it out at the front.

Moore led in the early laps before pitting to hand over to Firth, who found it impossible to maintain the pace during his stint due to over-used tyres.

The Ginetta duo traded the lead with Gary Simms, who was called back to the pits for a stop/go penalty after missing the pit window time limit.

Simms drove spectacularly after serving the penalty to close down Firth’s ten-second lead and pass him once again.

Firth said: “It was a great battle over the last two or three laps.

“I think we must have swapped the lead four or five times. It was brilliant. I only just managed to make the lead stick. On the last lap I had a good run, throwing caution to the wind, and managed to pull a gap on him. That little extra bit of bravery helped.”

Moore and Firth now enjoy a 12-point title race advantage as the championship heads towards the Rockingham circuit in Northamptonshire on May 30 and 31.
