Two podium finishes strengthened Ross Jamison's lead in the Formula BMW Pacific championship as the Hong Kong driver took second in round eight and finished first in round nine during yesterday's two races at the Sentul International Circuit in Indonesia. The 18-year old leads the championship by 15 points at the half-way point of the 16-round series. 'It's a really nice feeling as we've had our ups and downs [this season],' Jamison said. The former King George V student believes he can win the series, which concludes in November at the Macau Grand Prix.
