Shelby Blackstock and Ashley Freiberg were awarded the win in Friday's IMSA Continental Tire SportsCar Challenge when race officials disqualified Turner Motorsports for a technical infraction in post-race inspection.
Turner Motorsport's No. 96 driven by Bill Auberlen and Paul Dalla Lana had originally been scored the winner, with the Fall-Line Motorsports team co-driven by Blackstock and Freiberg finishing second until the final results were overturned.
The infraction was not revealed.
Freiberg became the first woman to win overall in Continental Tire Challenge history. It's also the first series win for Blackstock, the son of singer/actor Reba McEntire.
Freiberg's win at Daytona International Speedway came nearly a year after Lara Tallman won a Street Tuner (ST) class race in the 2013 BMW Performance 200 at the famed track.
