Sonoma, CA -- Michael Whelden qualified on pole in the TC class at the USTCC round 5 at Sonoma Raceway on September 27, 2015 in his Life's Good Racing/Hawk Mitsubishi Lancer but a huge crash between his car and a spinning GT car in front of him at Turn 1 in the first lap looked like bad news until he was informed that he was the winner. The crash was so severe that it took over 30 minutes for the NASA Safety Crew to clean up the mess and since the race was at the end of the day, there was no time to continue so the officials were forced to award finishing positions according to the starting grid. Second place went to Patrick Chio's Speed SF Nissan 350Z while Rod Rojas took the third place position driving the GoGoGear.com/UTI/Konig Wheels Hyundai Genesis Coupe.
In the GT class, Dave Brown secured the win in the Hawk/Competition Clutch Chevrolet Camaro while Daniel Akhromstev's Red Star Racing BMW M3 finished second and Felipe Loza's Pepster Chevrolet Camaro finished third. The Sportsman category was won by GoGoGear.com/UTI BMW M3 of Roger Eagleton while Tom Milburn finished second in the Bay Area Drafting Acura RSX and Becky Arsham finished third in the GoGoGear.com/UTI/Konig Wheels Honda Civic.
