The 39-year-old pensions actuary finished third and second in the final rounds at Silverstone National circuit on Sunday.

Fraser led the single-seater championship after a snowy opening weekend at Brands Hatch and was never headed throughout the 12-round series. He ends the season with four wins and a notable record of finishing every race in the top three, while his final margin of victory is 23 points after nearest rival Steven Durrant failed to finish either race at Silverstone.

Holding a slender two-point lead heading into the last weekend, Fraser qualified second and third during Saturday's qualifying session only 0.05 and 0.04 seconds from pole position and would start behind Durrant in both races. A downpour on Sunday morning led to a delayed programme and difficult wet conditions for round 11.

The Kilsyth-based SmartCats Consulting-backed driver struggled for grip in the 14-lap race and was some distance behind winner Ed Heinzelmann and second-placed Adrian Dixon. However, a spin for Durrant on lap two meant Fraser began the second race assured of the title.

Commenting on his achievement, 2008 Formula Renault BARC Championship Club Class champion Fraser said: ""I'm delighted to take the title as both the team and I have worked really hard all season to be consistently good. It's a shame Steven had such a poor final round as I know we both would have preferred to have taken it to the wire, particularly as we've raced so closely all season."

After winning the last Club Class championship of the current era,, Fraser is now considering a step up into the modern FR2.0 car as the championship becomes a one-make class in 2009.

Formula Renault BARC Championship Club Class standings after the final round were: 1, Fraser Smart, GBR Driver, 147 points; 2, Steven Durrant, GBR Muzz Race, 124 points; 3, Edward Heinzelmann, GBR Heuthsports of Royston, 121 points.
