Tasman Motorsport's debut event with new major partner, Rockstar Energy Drinks, was a success for the Preston team after Jason Richards finished third in the final race in the Falken Tasmania Challenge.

Starting from tenth on the grid for race two, Richards finished the final two sprint races in seventh and third - allowing the New Zealander to claim a strong sixth place overall as the second best performing Holden driver for the weekend.

"Third in the final race and sixth overall is a good result for the effort put in after a disappointing qualifying," said Richards.

"We had a strong race package, which kept getting better as the event went on, while our stops were on the pace.

"After a difficult Bahrain, it was good to be back on the pace again."

Richards' team mate, Greg Murphy, endured a tough final day at Symmons Plains, being spun at the circuit's tight hairpin once in each race. The incidents saw the four-time Bathurst winner drop to twenty-second place in race two, and fifteenth in race three.

"To be punted off twice in exactly the same spot, in the same manner, in two different races and have our weekend wrecked is very, very disappointing," said Murphy.

"The entire ROCKSTAR Tasman team deserved better and there's really not much more you can say about it."

After this weekend's penultimate round of the championship, Murphy and Richards are ranked thirteenth and fourteenth on the series points table, with the final round of the 2007 title to be held in a fortnight at Phillip Island for the Dunlop Grand Finale.
