Extra Weight added to COT's at Sonoma: NASCAR teams will be adding extra weight to the cars of tomorrow [COT] this weekend at Infineon Raceway. NASCAR has increased the weight of the car by 50 pounds to allow teams to distribute the weight more easily and to improve the integrity of the car since teams will not be trying to lighten up the car in other places, a NASCAR spokesman said. The new weight of 3,450 pounds is in place for all car of tomorrow races going forward.(SceneDaily.com)(6-23-2007)
