SONOMA, Calif. – Chris Dyson left fans stunned on Sunday during the Trans-Am Series Presented by Pirelli West Coast race at Sonoma Raceway after the New York native drove from the back to the front of the 29-car field twice to claim his first West Coast victory. Three different class cars led during the 100-mile race, but it was Dyson in the 850-horsepower TA car who claimed the checkered. CD Racing finished one-two overall as its National series TA driver Humaid Masaood finished second overall and second in class after starting eighth in the No. Dyson broke Pickett’s Sonoma Trans-Am lap record during qualifying on Saturday, beating the standing time by more than two seconds. Joiner later pitted for slicks and returned to the race to take second in class and 22nd overall. Trans-Am ProAm Challenge driver Mayer finished first in class and fourth overall in the No.
