The Nitto Tires United States Touring Car Championship teams started the 2015 season with the most difficult race of the year, a day-into-night, two-hour-long enduro at Southern California’s Buttonwillow Raceway on April 18, 2015.
In a race that started with the pole sitter’s time being disallowed for non-working GPS data, the action was nonstop for two hours. It seemed like many cars had mechanical issues and more than a few suffered flat tires and some ran out of fuel. At the end, Jason Alexandridis ended up finishing first in the TC class in the TNI Racing BMW M3, but he was disqualified for being underweight after the race. The win then went to Beau Borders in the Comp Clutch/Hawk BMW M3. Second was the team of Patrick Chio and Andrie Hartanto. Third place went to Karl Chicca in the second Comp Clutch/Hawk BMW M3.
In the GT class, Mike Holland/Steve Lisa finished first in the Mendeola Powertrains Factory Five GTM just seconds over V.J. Mirzayan and his Achilles Motorsports BMW M3. Due to a timing and scoring issue during the race, Mirzayan was granted 10 additional points after the race. Daniel Akhromstev finished third in the Red Star Racing BMW M3. Overall, USTCC winners collected about $10,000 in prizes.
