Not only Sarosh secured the drivers' title, his team Chennai-based Dark Don Racing also won the championship.
Race one winner was Vishnu Prasad, who was second coming into this round, just one point ahead of Kartik Krishna.
There was nothing to separate the front runners but as the race progressed Vishnu Prasad had better pace as the Meco Racing driver started pulling away. He was closely followed by Kartik and Ameya Bafna.
The second race turned out to be an more exciting affair as the first five cars went side-by-side in the opening few laps. Hataria went into lead which he preserved till the flag.
