The Confederation of the Australia Motor Sport's decision to revise the results of race three from round 12 of the V8 Supercar Championship in Tasmania last weekend has had a mixed effect on Stone Brothers Racing.

The decision to award the race win to David Besnard and the minor placings to Jason Bright and Mark Skaife has seen all the Tasmanian results vary.

The placing of those three drivers means that the originally declared race three winner, Greg Murphy, is relegated back to fourth and he, and the majority of drivers behind him, drop six championship points as a result.

The new race three results do not change the top three overall positions from Tasmania where Russell Ingall won the round in his SBR-prepared Caltex Falcon from Murphy and Steve Richards.

The new results give SBR's Marcos Ambrose an extra-six point buffer and means that he now only has to finish no more than 15 places behind Murphy or 20 places behind Bright in any of the final round's three races at Eastern Creek in a fortnight to clinch back to back titles in his Pirtek Falcon.

The reversal of the decision means that Bright comes back into third place in the championship and Ingall drops back to fourth.

Ingall still has second place in the championship in his sights, but now also has Bright as well as Murphy between himself and that goal.

"The whole thing has been pretty confusing," said Ingall. "At the end of the day the points gap between me and Murphy has not changed, but now Bright is back in the mix.

"We are still focused on second place in the championship and we will be going all out at Eastern Creek to achieve that goal. We have got nothing to loose."
